The human eye may only be capable of seeing a small fraction of the electromagnetic spectrum that comes off the sun, but without this ability to see visible light portion of the spectrum we would be unable to function. Show Me Science: The Science of Light studies the light that the sun produces, and its effects on Earth's life forms. The program also demonstrates how a solar eclipse takes place, how light is reflected and seen by the human eye, and how light is much more than just a visual medium in its use as a communication tool in lasers.
