1. A repeating motion that occurs in cycles:

• Frequency

• Wave speed

• Harmonic motion

• Medium

A disturbance that transfers energy through a medium from one location to another:

• Wave

• Trough

• Equilibrium position

• Period

A wave vibrating perpendicular to the direction the energy is moving:

• Transverse wave

• Longitudinal wave

• Pulse wave

• Compression

A wave vibrating in the same direction as the energy it moves:

• Pulse wave

• Longitudinal wave

• Trough

• Crest

The highest point on a transverse wave:

• Crest

• Trough

• Rarefaction

• Compression

The lowest point on a transverse wave:

• Trough

• Crest

• Medium

• Wavelength

The region in a longitudinal wave where particles are closest together:

• Trough

• Medium

• Compression

• Rarefaction

The region in a longitudinal wave where particles are farthest apart:

• Crest

• Rarefaction

• Wavelength

• Transverse wave

A single disturbance that moves through a medium:

• Pulse wave

• Wave speed

• Amplitude

• Period

The distance between two corresponding points on a wave, such as crest to crest:

• Wavelength

• Period

• Amplitude

• Compression
