Read wavelength from position graph
A displacement-position graph from a harbour wave model shows the horizontal distance from one crest to the next is \(0.5\,\text{m}\). Calculate the wavelength. 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.
Write a full answer
Now write the response in full, in your own words — this is what the exam asks for. The AI marks it on the same moves you built above (focus, evidence, technique, judgement) and gives feedback on reasoning, evidence, and expression.
