White light, for example, is a form of radiant energy, and its frequency forms a tiny bit of the entire electromagnetic spectrum. In the illustration above, you will see the different radiant energy levels represented by their wavelengths.

This radiant energy is necessary for the metabolism of the environment and its inhabitants 1. The three relevant bands, or ranges, along the solar radiation spectrum are ultraviolet, visible (PAR), and infrared.
