(a(i))[1]
Define, for a wave, the meaning of displacement.
(a(ii))[1]
Define, for a wave, the meaning of wavelength.
(b(i))[1]
Use Figs. 5.1 and 5.2 to determine the vibration period T for the water wave.
(b(ii))[1]
Use Figs. 5.1 and 5.2 to determine the wavelength $\lambda$ for the water wave.
(b(iii))[2]
Use Figs. 5.1 and 5.2 to determine the speed $v$ of the water wave.
(c(i))[2]
Use Figs. 5.1 and 5.2 to state and explain whether the wave loses power as it moves away from the source.
(c(ii))[3]
Determine the ratio $\frac{\text{intensity of wave at source}}{\text{intensity of wave } 6.0\,\text{cm from source}}$.
