Back

Crest

Front

What type of wave moves back and forth parallel to the direction it is traveling?

Back

Longitudinal wave

Front

What is the term for a change in the direction of a wave when it encounters an obstacle?

Back

Diffraction

Front

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

Back

Frequency

Front

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

Back

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