visible light

The part of the electromagnetic spectrum that humans perceive. The infrared and ultraviolet bands precede and follow visible light. See visible light communication.


Visible Light
Our eyes perceive a tiny sliver of the electromagnetic spectrum. The wavelengths from (approximately) 400 to 750 nanometers provide us with our view of the physical universe.
