1. What do waves transmit?

2. What type of wave is shown below?

3. The questions below refer to this diagram.

(a) Calculate the wavelength of the waves shown.

(b) What is the amplitude of these waves?

4. 24 water waves pass a point in 6 seconds. What is the frequency of the waves?

5. A wave of wavelength 2 m travels 60 m in 12 seconds.

(a) What is the speed of the wave?

(b) How many waves would be produced in 12 seconds?

(c) What is the frequency of the wave?

6. Two students watch the waves produced by a wave machine at a swimming pool.

One student walks beside a wave as it travels along the pool.
The wave goes from one end of the pool to the other in 20 s.
The length of the pool is 24 m.
(a) Calculate the speed of the waves.
(b) In the same time interval, the other student counts 5 waves going past the point where he is standing.
Calculate the frequency of the waves.
(c) The students note that there are 5 complete waves in the pool at anytime. Calculate the wavelength of the waves.
