A water wave passes into a region where the wave travels more slowly.

As it passes into the slow region, what happens to the frequency and what happens to the wavelength of the wave?

 Which row shows the natures of light waves, sound waves and X-rays?

The diagrams show water waves that move more slowly after passing into shallow water.
Which diagram shows what happens to the waves?

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?

The diagrams represent water waves in a tank.

Which diagram represents a wave that changes speed?

The diagram shows a side view of a water wave at a particular time. The diagram is drawn full size.

Which statement about the wave is correct?

The diagram shows a water wave approaching a barrier with a gap.
The wave reaches point P.

What is the name of the effect that causes the wave to reach point P?

The diagram represents a water wave.
Which row shows the amplitude and the wavelength of the wave?

Which row correctly defines a type of wave and gives a correct example?

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?

A small boat in a harbour is protected from waves on the sea by harbour walls.
Some waves can curve round the harbour walls and reach the boat.

What is the name of this effect?

The diagram shows four waves drawn to the same scale.

Which statement is correct?

Which waves are longitudinal?

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?

Radio waves are received at a house at the bottom of a hill.

The waves reach the house because the hill has caused them to be ........
