): Represents how much light is lost to absorption as it travels through the solid. 4. Important Optical Phenomena
In the infrared range, light interacts directly with the vibrations of the crystal lattice (phonons). 5. Applications in Technology Optical Properties of Solids
When a solid absorbs energy and re-emits it as light (e.g., LED lights). ): Represents how much light is lost to
In semiconductors, an absorbed photon can create a bound electron-hole pair called an exciton, which dominates the optical spectrum at low temperatures. LED lights). In semiconductors
Anti-reflective coatings on glasses use thin-film interference to "cancel" reflected light.
Designed with semiconductors that have band gaps optimized to absorb the solar spectrum.
