What is frequency in sound waves?

Back

Frequency is the number of waves that pass a point in one second, determining the pitch of the sound.

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

True or False: The distance between wave crests is called amplitude.

Back

False. The distance between wave crests is called wavelength.
