A transverse water wave travels to the right. The diagram shows the shape of the surface of the water at time t = 0. P and Q show two corks floating on the surface.
State what is meant by a transverse wave.
[1]
«A wave where the» displacement of particles/oscillations of particles/movement of particles/vibrations of particles is perpendicular/normal to the direction of energy transfer/wave travel/wave velocity/wave movement/wave propagation ✓
Allow medium, material, water, molecules, or atoms for particles.

The frequency of the wave is 0.50 Hz. Calculate the speed of the wave.
[1]
v = «0.50 × 16 =» 8.0 «m s−1» ✓

Plot on the diagram the position of P at time t = 0.50 s.
[1]
P at (8, 1.2) ✓
Show that the phase difference between the oscillations of the two corks is radians.
[1]
ALTERNATIVE 1
Phase difference is × ✓
«= » ✓
ALTERNATIVE 2
One wavelength/period represents «phase difference» of 2 and «corks» are ½ wavelength/period apart so phase difference is /OWTTE ✓
