In Light, young Olive and her cousin Troy learn all about the properties of light with the help of a visiting inventor and a room full of his crystal trophies. They discover that light behaves in different ways to change the way we see things. When light waves hit something, three things can happen, the light can bounce, it can pass through or it can be absorbed. Troy, Olive and the inventor also examine a variety of devices which use lenses to bend light and help us see images correctly, such as telescopes, periscopes, and binoculars.
