- Light is a form of electromagnetic wave and constitutes a small part of the electromagnetic spectrum that is visible to the human eye. Hence, it is called visible light. Since visible light is a form of a wave, it is defined by its characteristic wavelength and frequency.

Jan 16, 2021 · The visible light spectrum is the region of the electromagnetic spectrum that human eyes see. It runs from wavelength of about 400 nanometers (nm) at the violet end of the spectrum to around 700 nm at the red end of the spectrum.
The spectrum of wavelengths we can see (visible light) ranges from 380 nm (blue) to 700 nm (red). Below this spectrum is ultraviolet, after which we have blue, and at the top of the spectrum of visible light is red, after which we have infrared.
White light is dispersed by a glass prism into the colors of the visible spectrum. The visible spectrum is the band of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light (or simply light).
Jun 7, 2024 · The wavelengths of visible light are: Violet: 380–450 nm (688–789 THz frequency) Blue: 450–495 nm; Green: 495–570 nm; Yellow: 570–590 nm; Orange: 590–620 nm; Red: 620–750 nm (400–484 THz frequency) Violet light has the shortest wavelength, which means it has the highest frequency and energy. Red has the longest wavelength, the ...

Mar 15, 2024 · Aside from using visible light to see, we’ve found many ways to make use of the different colors of light in the visible spectrum. For example, blue light is used for digital screens, while blue, blue-green, and green lights are used to treat jaundice through phototherapy.
