Wavelengths visible light

The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light from 400-700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it.Light outside of this range may be visible to other organisms but cannot be perceived by the human eye wavelengths of visible light All electromagnetic radiation is light, but we can only see a small portion of this radiation—the portion we call visible light. Cone-shaped cells in our eyes act as receivers tuned to the wavelengths in this narrow band of the spectrum Not coincidentally, this visible light window matches with the 'optical window', which is the range of wavelengths that pass through Earth's atmosphere, without attenuation or absorption. Life on Earth has evolved to perceive in these wavelengths, as they are the only components of sunrays, that do not get filtered out by the atmosphere

The colour of visible light depends on its wavelength. These wavelengths range from 700 nm at the red end of the spectrum to 400 nm at the violet end

Ultraviolet, or UV, light gets its name from the fact that its wavelengths are shorter than violet visible light. Its wavelengths lie in the range of 10 to 350 nanometers and come in several bands, such as UVA and UVB. The sunlight that reaches the Earth's surface has naturally-occurring amounts of UV Wavelengths. Visible light has a wavelength that ranges from 380 nm - 750 nm on the electromagnetic spectrum while infrared light is just beyond it, ranging from 700 nm - 1 mm, the start of the non-visible portion of the spectrum. As a result, infrared cannot be seen except with special equipment like a security camera Smartphones use visible wavelengths to light up the screen display. Your phone talks to other phones via radio waves. And the camera has the ability to detect infrared light that human eyes cannot see. With the right app, the phone transforms this infrared light into visible light that we can see on the phone's screen The visible spectrum (or sometimes called the optical spectrum) is the part 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.. A typical human eye will react to wavelengths in air from about 380 to 750 nm.. The familiar colors of the rainbow in the spectrum include all those colors.
