The light energy we perceive is only a small portion of light and radiant energy that exists. Readers discover how light travels in waves and how different frequencies of light waves comprise the different forms of light energy that form the electromagnetic spectrum. Photographs help illustrate the measures of light energy, and how the eyes work, and sidebars highlight important technology associated with light energy.
