### Difference Between Frequency and Wavelength

Frequency and wavelength both quantities that come in the study for electronics science. In everyday usage the two terms may have similar connotations, however, in electronic science, the two terms have two separate meanings. Here this article gives the main key difference between them to better understand this topic.

### Definition of frequency:

Frequency is defined as the number of vibrations or oscillation present in a wave in a unit time. The SI unit of measuring the frequency is hertz, shortly written as Hz.

### Definition of wavelength:

The minimum distance between two consecutive identical wave points is known as the wavelength. As it specifies the distance thus its SI unit is meter.

## The main key difference between frequency and wavelength:

• Frequency measures the time whereas wavelength measures the distance.
• The completed wave in unit time is called frequency, while the total length of the complete wave is called the wavelength.
• Frequency is denoted by f, while the wavelength is denoted by λ.
• Hertz is the measuring unit of frequency, while a meter is the measuring unit of wavelength.
• Frequency defined the total number of occurrence of oscillations in a unit time. While wavelength is defined as the length of a wave.
• Frequency also called the inverse of the time period, the wavelength is called distance covered by the wave.
• Frequency is the number of times in which the sound wave occurs, while the wavelength is the distance between sound waves.
• Frequency is a measure of time, the wavelength is a measure of distance.
• An audible sound wave possesses a frequency range of 20 to 20 kHz, but the wavelength of visible light range from 400 to 700 nm.
• Frequency is used to measure the recurrence of the sound wave, the wavelength is used to measure the length of sound waves.
• In relation to speed, frequency is the ratio of speed and wavelength, while wavelength is the ratio of speed and frequency.
• Frequency can be determined by the number of times sound hits a peak or through, while wavelength can be determined depending upon the crests, troughs, or zero-crossings through which sound passes.

### Difference Between Diffraction and Interference

Diffraction and interference both quantities that come in the study for mechanics. In everyday usage the two terms may have similar connotations, however, in electronic science, the two terms have two separate meanings. Here this article gives the main key difference between them to better understand this topic.

Definition of Diffraction:

Diffraction is the phenomenon of spreading of the light wave when it passes through a slit or any small gap.

Definition of Interference:

Interference is the act of superposition of two or more light waves emitted two coherent sources traveling in the same medium. We know the coherent sources provide a light wave of the same frequency and constant phase difference.

The main key difference between diffraction and interference:

• Diffraction. there is a variance of the intensity of positions, In interference, the intensity of all the positions on maxima are of similar intensity in interference.
• In Diffraction, the width of the fringes is not equal in interference, While the interference the width of fringes in interference is equal to the interference.
• In the case of diffraction, there is a variance in the intensity of interference, It is absolutely dark in the region of minimum intensity in case of interference.
• Diffraction can be termed as the secondary waves that emerge from the different part of the same wave, Interference may be defined as waves emerging from two different sources producing different wavefronts.
• For diffraction to take place slit or obstacle is necessarily required but for the wave interference there exists no such requirement.
• If the number of sources is many, that is more than two then it is referred to as diffraction sources, If the number of sources is few such as two sourced, then they are referred to as interference sources.
•  The diffraction process is poor contrast between maxima and minima while interference exhibits good contrast between maxima and minima.
• The direction of propagation of wave gets changed, whereas in case of interference the superposed wave travels in the same direction.
• Diffraction is the result of light propagation from distinct parts of the same wavefront, while interference is the result of the interaction of light coming from two separate wavefronts.
• The minimum intensity points in the case of diffraction are not completely dark, as against in case of interference the point of minimum intensity shows complete darkness.
• In diffraction superposition of waves spreading in the same material environment, while interference waves stray from the original route in the same elastic environment.
• In direction between different fringes is nonuniform in diffraction, while in the case of interference the spacing between the fringes exhibits uniform nature.
• Diffraction there is a constant phase difference between the waves, while in interference the dimension of the cracks should be the same size as the wavelength.

### Difference Between Distance and Displacement

Difference between distance and displacement is one of the most commonly asked and confusing equations in the subject of physics. Also, equations like differentiating between distance and displacement are very common in the exams. Here this article gives information about the main key difference between distance and displacement to better understand this topic.

Definition of Distance:

Distance is a word that derives the Latin word called "distanceia" which means being far away, Distance is a magnitude that measures the proximity relationship between two things, objects, bodies, etc. It can also be considered as the length that traveled by an object from one point to another.

Definition of Displacement:

Displacement is considered a vector magnitude and we can describe it as the variation of the position of a body. The displacement focuses on the length of the path of an object the exists considering an initial point and another endpoint. It can be said that the result is a straight line between these two points.

Difference between distance and displacement are listed below:

• Distance is denoted by d, While displacement is denoted by s.
• The complete length of the path between any two-point is called the distance, while the displacement is the direct length between any two points when measured along with the minimum path between them.
• The distance can only have a positive value, displacement can be positive, negative, and even zero.
• Distance is a scalar quantity as it only depends upon the magnitude and not the direction, displacement is a vector quantity as depends upon both magnitude and direction.
• The calculated distance, the direction is not considered in distance, while the calculated displacement, the direction is taken into consideration.
• The distance is calculated by speed *time while the formula of displacement calculates by velocity*time.
• Distance is the gives the detailed route information that is followed while traveling from one point to another, As the displacement refers to the short path, it does not give complete information of the route.
• Both are measured in meter(m).
• The distance can be measured along a non-straight path, displacement can only be measured along a straight path.
• Distance is not indicated with an arrow, displacement is always indicated with an arrow.
• Distance depends upon the path, displacement does not depend upon the path and it only depends upon the initial and final position of the body.
• Distance always covered whenever there is a motion, displacement will be zero if the body comes back to its initial position.
• The total distance covered is equal to the algebraic sum of all the distance traveled in a different direction, the net displacement is the vector sum of the individual displacement in a different direction.

### Difference Between Slip Ring and Split Ring

Slip and split rings both are basically two different ways of making a connection between a stationary and a rotating object for the current to flow through them. Here this article give the information about the main key difference between slip ring and split ring to better understand this topic.

### Definition of slip ring:

The slip ring is a part of a basically AC motor use for transmission of the energy between the stationary and rotating elements of the machine. And the graphite material uses for the manufacturing of brushes. It is a place on the outer surface of the slip ring.

### Definition of split ring:

On the other hand, the split ring is a movable device used for reversing the polarity of the current. It is made of basically copper materials. The ring devices from the centre into two halves. The combination of the split ring and brushes is known as the communicator. The split ring uses basically DC motor for getting the pulsating input voltage.

## The main key difference between the slip ring and split ring:

• The slip ring used for transferring the power from stating and rotary parts of the machine, while the split ring uses for changing the polarity of the current.
• The slip ring is used in the AC machine but, the split ring uses in the DC machine.
• The slip ring is in the form of a continuous ring, and the split ring splits into two or more parts.
• The slip ring is supplied from an AC generator to the AC motor, for supplying pulsating voltage to the DC motor.

### Difference Between Physical and Logical Topology

A physical topology is how they are actually interconnected with wires and cables, While in a logical topology is how devices appear connected to the user.  Here this article give the information about the main key difference between physical and logical topology to better understand this topic.

### Definition of the physical topology

Physical topology can be considered as a layout of the network media that shows the interconnection of the devices on the network. It specifies which geometric shapes the linked devices form with each other. The physical topology does not give much impressive detail about te type of devices, the mechanism used for interesting with other devices in the network, and how data is transferred from one device to another.

### Definition of logical topology

While comparing to the logical topology emphasis the manner in which data is transmitted between network nodes instead of the physical layout of the path that data follows. The most important fact regarding these topologies is that both physical and logical topologies are independent regarding a  comparing network, whether it of any shape and size.

## Difference between physical and logical topology:

• The physical topology is basically the physical layout of the network media. In contrast. logical topology refers to the way, how data is transmitted through the network.
• Physical topology refers to how a network look and functions, while in logical topology fashion in which data travels logistically.
• Bus, star, ring, and mesh are the physical topology, logical bus and the logical ring are the logical topologies.
• While using logical topology is intangible in nature while physical topology can be customized.
• The physical topology would not hider the transmission of the data from one device to the other in a logical topology.
• Physical topology is costly, scalability, and flexible while in logical topology data delivery causing loss.
• The physical connection of cable and devices in called as physical topology, while in path travel by data in a network called logical topology.

### Difference Between Resistance and Reactance

The main key difference between resistance and reactance is that the resistance measures the opposition to a flow of current, whereas reactance measure the opposition to change in current. Here this article give the information about the main key difference between resistance and reactance to better understand the topic.

### What is resistance?

The resistance of a component in a circuit is the potential difference across the component devices by the current through the component.

### What is reactance?

Reactance is totally opposed to a change in current. Reactance is a property of capacitor or inductor because its functionality is intimate to the rates of changes of current and voltage.

## The main key difference between resistance and reactance:

• The resistor is associated with the real part of impedance, But in reactance contributes to the imaginary part of the impedance value.
• Pure resistor generates resistance, while ideal inductors or capacitors give rise to resistance in the circuit.
• Resistor depends upon the conductor's dimension, resistivity, and temperature, while the reactance depends upon the frequency of the alternating current.
• Resistance is defined as the R, while the reactance is defined as the X.
• Resistance is the property associated with the both AC and DC circuit, However, reactance to the property is only associated with AC circuits.
• The resistance is the obstacle in the flow of current in an electrical circuit due to resistor, while reactance is the opposition to the charging current due to either inductor or capacitor.
• In the resistive circuit, the overall supplied power to the circuit gets dissipated in the form of heat, Whereas in a capacitive or inductive circuit the device does not fully consume the total supplied power.
• The difference in phase between voltage and current in a purely resistive circuit is 0 degree, while the phase difference between voltage and current in an ideal capacitive or inductive circuit is 90 degrees. In the case of inductive load, the current lags behind the voltage by 90 degrees and for purely capacitive load voltage pages the current by 90 degrees.
• The resistance offered by the circuit depends on the dimension, resistivity, and temperature conditions of the conductor, while the reactance relies on the frequency component of the alternating current in the circuit. It shows the proportionality with frequency in case of inductive load, whereas this relation is inverse in case of capacitive load.
• Power consumption due to resistance is real power and it is a product of voltage and current, While the power supplied to a reactive device is not fully consumed by the device due to lagging or leading current.

### Difference Between Client-Server and Peer-to-Peer Network

Both network are depends on the environment which network model to implement, each model has its own strength and flaws. Here this article gives information about the difference between client-server and peers to peer networks to better understand this topic.

### What is a client-server network?

The client servers network focuses on information sharing. Though the server can share its resources with clients, clients do not share their resources such as computing power on hard drive space with the network.

### What is a peer to peer network?

A peer to peer network is a group of computer or computer systems that are connected to each other through the internet. Files can be shared directly between their systems on the network without the need for a central server.

## The main key difference between client-server and peer to peer network:

• In the client-server model, data is stored on a centralized server while in peer to peer each peer has its own data.
• Client-server networks main focus on information sharing, while peer to peer model focuses on connectivity.
• In the client-server model, there is a dedicated server and specific clients, While in Peer to peer each node can act as both server and client.
• In the client-server model, sharing the information is more important, but in peer to peer model connectivity between peers is more important.
• In the client-server model, the server provides services to the client, In peer to peer can provide service and can also request for the services.
• In client-server network client and server both are differentiated, specific server and client and present, While in peer to peer client and server are not differentiated.
• The client-server model is more expensive to implement than peer to peer networks.
• The n client-server model,  model is more scalable and stable than peer to peer.
• A client-server network is used for both small and large networks, While in peer to peer network is generally suited for a small network with fewer than 10 computers.
• The client-server model is less reliable, while in peer to peer network is more reliable.
• In client-server multiple requests for service from a server and therefore, the access time for a service is higher, While the service providing nodes are distributed, in peer to peer network, the service requesting node does need to wait long.
• Client-server network very much secure when compared to the peer to peer network, while in peer to peer network is less secure when compared to client-server network.
