What are breaking waves?

• waves that move in circles

• waves that bob up and down

• waves that move from side to side

• waves that fall forward with a splash

In which of these waves does matter move only from side to side?

• water waves

• sound waves

• surface waves

• waves on string

The point where the matter carrying a sound wave is spread apart is known as the wave’s _________.

• rest position

• loudness

• crest

• trough

Water waves, waves on a string, and sound waves all

• move in circles.

• move from side to side.

• push matter together and spread it apart.

• spread out in all possible directions.

Which of the following describes the wavelength of a water wave?

• the distance from crest to trough

• the distance from trough to rest position

• the distance from trough to trough

• the distance from rest posion to crest

A wave with a large amplitude

• must have a low crest.

• must have a long wavelength.

• must have a high crest.

• must have a short wavelength.
