the amplitude cannot be determined

Answer 1

I can’t see the student’s drawing — please upload the image or tell me the vertical positions of the crest and trough.

How to find it: amplitude = the maximum displacement from the equilibrium (middle) line = half the distance from crest to trough. So
- amplitude = (crest − trough)/2.

Examples:
- If crest = 1 m and trough = −1 m → amplitude = (1 − (−1))/2 = 1 m.
- If crest = 2 m and trough = −2 m → amplitude = 2 m.
- If you don’t know the vertical scale or the equilibrium position, then the amplitude cannot be determined.
