Optical: Properties Of Solids

): Represents how much light is lost to absorption as it travels through the solid. 4. Important Optical Phenomena

The most critical factor in a solid's optical behavior is its . Insulators and Semiconductors: These have a "band gap" ( Egcap E sub g ). If a photon's energy ( ) is greater than Egcap E sub g Optical Properties of Solids

Understanding these properties allows us to engineer materials for specific tasks: ): Represents how much light is lost to

Made of ultra-pure glass with extremely low absorption ( ) to carry data over thousands of miles. Optical Properties of Solids

An increase in electrical conductivity caused by light absorption (used in light sensors).
