What is the number of wavefronts per second that pass a fixed point?
A the amplitude of the wave
B the frequency of the wave
C the speed of the wave
D the wavelength of the wave
The diagrams show two water waves P and Q that are travelling at the same speed on the surface of a pond.
The diagrams are to the same scale.
Which wave has the greater amplitude and which wave has the greater frequency?
A water wave moves quickly in deep water.
The wave now enters shallow water and its speed decreases.
Which row shows what happens to the frequency of the wave, and what happens to the wavelength of the wave?
The diagram shows a water wave passing through a gap in a harbour wall. The wavefronts curve round the wall and reach a small boat in the harbour.
What is the name of this curving effect, and how can the gap be changed so that the wavefronts do not reach the boat?
Waves travel more quickly on the surface of water when the water is deep.
A stone is dropped at point X into a pool of varying depth. The diagram shows the first wavefront on the surface of the pool.
The region between X and which labelled point is likely to be the deepest?
