When two or more waves combine to produce a wave with smaller displacement.

• constructive interference

• destructive
  interference

• diffraction

• refraction

A wave that appears to stay in one place.

• standing wave

• node

• antinode

• diffracting wave

A point on a standing wave that has no displacement from the rest position.

• node

• antinode

• standing node

• constructive node

A point where a crest or trough occurs midway between two nodes.

• mid-node

• antinode

• standing node

• constructive node

When a wave enters a medium at an angle​ (a)   occurs because one side of the wave moves more slowly than the other side.
