It is the part of the spectrum that is detected by the human eye. It runs from about 4×1014Hz to about 7×1014Hz 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.
