Wave Interactions Flashcards

All 5 cards in this deck

Name the four things that can happen to a wave at a boundary between two materials.: Reflection, refraction, transmission and absorption.
What happens to a wave that is reflected at a material interface?: It bounces back off the boundary and stays in the first material.
What happens to a wave that is transmitted at a material interface?: It passes through the boundary and carries on travelling in the second material.
What happens to a wave that is absorbed by a material?: Its energy is transferred to the material's energy stores (often heating it), so the wave is not transmitted.
True or false? When a wave is absorbed by a material its energy is destroyed.: False. The energy is transferred to the material (usually to its thermal energy store).
