Background Information

Light is needed for humans to see. Light may also be used to communicate. As with sound, the type of medium used for passing the light through will be determined by the function of the communication. For example materials used in stoplights, stained glass windows, flashlights, and frosted glass all affect the output of light. When light strikes an object, many actions may occur. Two factors involved in this interaction are the type of light and the object itself. The light may bounce or reflect off of an object or pass through it. The quality of light transmission may determine the use of a material.
