The bending of waves when they pass around a barrier or through an opening

Diffraction

The bending of waves when they pass around a barrier or through an opening is called diffraction. It's like when water waves bend around a rock in a pond.

A reflected sound wave

Echo

A reflected sound wave. Echo. An echo is when sound waves bounce off a surface and return to your ears, so you hear the sound again.

States that the angle of incidence is equal to the angle of reflection

Law of reflection

States that the angle of incidence is equal to the angle of reflection. Law of reflection. The law of reflection explains that when light hits a surface, it bounces off at the same angle it arrived.
