Some plane water waves were produced in a ripple tank. They pass from a region of deep water into a region of shallow water. Figure 15.0 shows what the waves look like from above.

State what happens at the boundary to
- the frequency of the waves
- the speed of the waves
- the wavelength of the waves
- The waves have a speed of 0.12ms-1 in the deep water wave crests are 0.08m apart in deep water. Calculate the frequency of the source producing the waves.
