How do humans see visible light waves
WebLight waves have wavelengths between about 400 and 700 nanometers (4,000 to 7,000 angstroms). Our eyes perceive different wavelengths of light as the rainbow hues of colors. Red light has relatively long waves, around 700 nm long. Blue and purple light have short waves, around 400 nm. WebVisible light is the small part within the electromagnetic spectrum that human eyes are sensitive to and can detect. Visible light waves consist of different wavelengths. 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.
