The range of electromagnetic radiation visible to the human eye. It is a narrow portion of the electromagnetic spectrum* encompassing energy with wavelength*s from around 400 nm (blue light) to 700 nm (red light).
The visible range of the electromagnetic spectrum is flanked by shorter wavelength ultraviolet energy on one side and the longer wavelength near-infrared energy on the other. Visible light includes energy in the range of the sun’s peak output which is roughly 580 nm (yellow light).
