Front

What is the highest part of a transverse wave called?

Back

Crest

Front

What is the lowest part of a transverse wave called?

Back

Trough

Front

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

Back

Wavelength

Front

What is the measure of the height of a wave from its rest position to its crest?

Back

Amplitude

Front

What is the term for the number of complete waves that pass a given point in a certain amount of time?

Back

Frequency

Front

What is the term for the regions of a longitudinal wave where particles are close together?

Back

Compression

Front

What is the term for the regions of a longitudinal wave where particles are spread apart?

Back

Rarefaction

Front

How do you calculate the frequency of a wave?

Back

Frequency = Number of waves / Time period (in seconds)

Front

If a wave has a frequency of 2 Hz, how many crests will pass a point in 5 seconds?

Back

10 crests (2 Hz * 5 seconds = 10 crests)

Front

What is the speed of a wave if its wavelength is 4 meters and its frequency is 2 Hz?

Back

Speed = Wavelength x Frequency = 4 m x 2 Hz = 8 m/s
