• 0.09 Hz

• 0.88 hertz

• 0.44 Hz

• 0.32 Hz

When a wave is travelling through matter, what happens to the matter?

• The matter is pulled along behind the wave as that makes it a longitudinal wave.

• The wave is making the matter move back and forth as that will make a transverse wave.

• The wave is making the matter move up and down.

• The matter is pulled along behind the wave as that makes it a compressional wave.

• The matter does not move along with the wave.

What happens to the matter at the node of a standing wave?

• The matter at the node is not disturbed by the wave.
