General properties of waves — practice question
Fig. 6.1 illustrates wavefronts moving towards a gap in a barrier.
(a(i))[2]
On Fig. 6.1, add three wavefronts on the right of the barrier.
(a(ii))[2]
On Fig. 6.2, add three wavefronts on the right of the barrier.
(b)[4]
Describe, with a labelled diagram, an experiment using water waves to demonstrate the reflection of wavefronts at a straight barrier.
Worked solution & mark scheme
This 8-mark question has a full step-by-step worked solution and mark scheme. One marking point: “At least 3 circular wavefronts centred on the gap, with each one reaching at least half a semicircle” …
