Back

amplititude

Front

part of a longitudinal wave where the wave pushes matter closer together

Back

compression

The highest point on a transverse wave

Back

crest

Front

A change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening

Back

diffraction

Front

A form of energy that can travel through empty space as well as through matter, includes visible light, radio waves, X rays, and many other wavelengths.

Back

frequence

Front

unit of measurement for frequency

Back

hertz

Front

The combination of two or more waves that results in a single wave

Back

interference

Front

a wave that moves back and forth parallel to the direction that it is travelling

Back
