Light and LasersBook - 2005 | New ed
Looks at the science of light, what it is, how it enables us to see, and what it does as it passes through a lens. Light travels faster than anything we know of. Some materials allow light to pass through them; others don't. When light is blocked in this way, a shadow is formed. Find out how the special light produced by lasers can vaporize metal and cut through diamonds.
