What is the term for the maximum displacement of a wave from its rest position?

Back

Amplitude

Front

What is the distance between two consecutive crests or troughs in a wave called?

Back

Wavelength

Front

What is the formula to calculate wave speed?

Back

Wave speed = Wavelength × Frequency

Front

What do you call the highest point of a wave?

Back

Crest

Front

What is the lowest point of a wave called?

Back

Trough

Front

What is the term for the region in a longitudinal wave where particles are spread apart?

Back

Rarefaction

Front

What is the term for the region in a longitudinal wave where particles are very close to each other?

Back

Compression

Front

What is the unit of measurement for frequency?

Back

Hertz (Hz)

Front

What is the relationship between frequency and wavelength in a wave?

Back

They are inversely related; as frequency increases, wavelength decreases.
