The role of light in perception

One of the most important sources of perception of the real the world is light. Light includes radio waves, microwaves, infrared light, ultraviolet rays, x rays, and gamma rays in addition to the visible light that is most familiar to humans. These other sources of light are essential to the astronomical perception of physical entities across the universe.

Through light we can get images and videos of the environment. With these perceptual stimuli we can begin to create spatiotemporal models of the environment. With the process of perceptual recognition we can give semantic meaning to stimuli by relating them to categories.
