Question 4

Why are the waves on the surface of water transverse waves?

A Because the water particles move up and down while the wave spreads across the surface B Because they need no medium C Because they are made by wind D Because the water flows towards the bank

The right answer is the one marked above.

Because the water particles move up and down while the wave spreads across the surface. Up and down is at right angles to across, which is what makes a wave transverse.

The water does not flow to the bank, and water waves do need their medium — the water.
