WE1 If the crest of a wave measures $2$ m above the still water mark in the harbour, what is the amplitude of the wave?(2)
Show the memo (2 ticks)Memo
1. ✓
  Equilibrium positionThe still water mark is the height of the water when there is no disturbance: it is the equilibrium position.

2. ✓
  AnswerThe crest is $2$ m above the equilibrium position, so the amplitude is $2$ m.
