Small water waves are created in a ripple tank by a wooden bar.
The wooden bar vibrates up and down hitting the surface of the water.
The figure shows a cross-section of the ripple tank and water.
Which letter shows the amplitude of the water wave?

K
L
How do oscillations move in a transverse wave?
Randomly
At right angles to the direction of wave travel
Parallel to direction of wave travel

Randomly
At right angles to the direction of wave travel
Parallel to the direction of wave travel
Which of these is an example of a transverse wave?
microwave
sound wave
seismic P-wave
What is the unit for time period?
metres (m)
Hertz (Hz)
seconds (s)
