The visible region of the electromagnetic spectrum is known as visible light. It is the range of wavelengths that causes humans to perceive brightness and colour. It is located between UV and infrared radiation and most people can visually detect wavelengths between approximately 400 nanometers and 780 nanometers. Here this article gives the application of visible light to better understand this topic.
What are the applications of Visible light?
- Photography: One of the use of visible light can be essential use for photography, as cameras capture light reflecting off objects to create images.
- Lighting: Visible light is utilised to provide lighting in a variety of locations, including public, outdoor, and residential areas.
- Medicine: Surgical techniques utilising lasers or other light-based technology, as well as light therapy for the treatment of specific skin problems and mood disorders, all make use of visible light.
- Communication: Optical communication systems, including fibre optic networks, employ visible light to send data at fast speeds via light pulses.
- Solar energy: Using photovoltaic cells, which turn sunlight into electricity, visible light from the sun is captured for solar energy production.
- Art and entertainment: Painting, theatre, film and light shows are just a few of the artistic and entertaining mediums that use visible light to create visual experiences and communicate ideas and feelings.
- Agriculture: The process of photosynthesis, which transforms sunlight into chemical energy utilised by plants for growth and reproduction, depends on visible light for plant growth.
- Spectroscopy: Based on the absorption or emission spectra of material and celestial bodies visible light spectroscopy is used in chemistry, physics and astronomy to identify elements and compounds and analyse their properties.
