(a(i))[4]
Draw a diagram of a ripple tank and explain how it is used to generate and observe the wave.
(a(ii))[2]
The water wave in the ripple tank transfers energy. Describe a way to show that energy is being transferred.
(a(iii))[2]
State the meaning of a wavefront.
(b(i))[2]
State one difference and one similarity between the two waves shown in Fig. 11.1.
(b(ii).1)[3]
The water wave travels at $0.20\,\text{m s}^{-1}$. Determine the frequency of wave P.
(b(ii).2)[2]
Find the wavelength of wave P.
