At its core, the response of a solid to light is determined by its ( ) and its dielectric function ( Optical Properties of Solids
When light strikes a solid, three primary phenomena occur: , absorption , and transmission . The balance between these depends on the material's internal electronic structure. Licensed by Google Made of ultra-pure glass with extremely low absorption
Light bouncing off the surface. Metals are highly reflective because their "free" electrons can oscillate rapidly to cancel out the incoming field. three primary phenomena occur:
