Properties and Uses of Visible Light



Visible rays

It is the part of the spectrum that is detected by the human eye. It runs from about to about or a wavelength range of about 700- 400 nm. Visible light emitted or reflected from objects around us provides us information about the world. Our eyes are sensitive to this range of wavelengths. Different animals are sensitive to different range of wavelengths. For example, snakes can detect infrared waves, and the visible range of many insects extends well into the utraviolet.
