Free Light / Optics Physics Help

Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. Light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not: gamma rays, X-rays, microwaves radio waves. Optics studies light and the interaction of light and matter. Optical phenomena (rainbows, aurora borealis) offer clues about the nature of light.
