Amplitude from a wave graph
A displacement graph from a standing-wave string practical has maximum displacement \(5\,\text{cm}\) from equilibrium. State the amplitude in centimetres. Enter the numerical result and choose the interpretation that matches the wave physics.
Worked practice: physics data and result
Read the physical quantities first, then calculate the result and state what it means.
