General properties of waves — practice question
Fig. 6.1 illustrates crests of a plane water wave moving toward a barrier that has a gap. The diagram is labelled crests, barrier, and direction of travel of water wave. Fig. 6.2 illustrates crests of a plane water wave in deep water as it moves toward a shallow-water region, with labels deep water, shallow water, boundary, and direction of travel of water wave.
(a(i))[2]
On Fig. 6.1, draw three crests of the water wave on the right-hand side of the barrier.
(a(ii))[3]
On Fig. 6.2, draw: 1. three crests of the water wave in the shallow water 2. the direction in which the wave travels in the shallow water.
(b)[2]
State two ways that transverse waves are different from longitudinal waves.
(c(i))[1]
State a typical value for the speed of sound in water.
(c(ii))[1]
Explain why sound travels more quickly in water than in air.
Worked solution & mark scheme
This 9-mark question has a full step-by-step worked solution and mark scheme. One marking point: “The wavefronts form semicircles centred on the gap” …
