The crest of a wave is its:

• Top

• Bottom

• Middle

• Frequency

The bottom of a wave is called the:

• crest

• trough

• wavelength

• amplitude

The amount of times a wave passes by a certain point in one second is called the:

• amplitude

• wavelength

• trough

• frequency

Wavelength is:

• The top-most point of a wave

• The amount of time a wave passes by a certain point in one second

• The distance from one wave crest to another

• The height and strength of a wave
