Interpret displacement-time and displacement-position wave graphs

Paper 1, Paper 2 5 marks Difficulty 5

Read amplitude from graph

In a second version of the same wave investigation, a displacement graph from a string vibrator experiment has equilibrium at \(0\) and crest displacement \(0.09\,\text{m}\). Calculate the amplitude. Use the diagram first, then calculate the requested value. Enter the numerical result and choose the interpretation that matches the wave meaning.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
