Question

What is the amplitude of the wave in the diagram below?

• A. 0.03 m
• B. 0.04 m
• C. 0.05 m
• D. 0.06 m

Answer 1

The correct option is A 0.03 m

The amplitude of a wave is measured from mean position to crest or from mean position to trough; but not from crest to trough. Thus, the height of the wave that is 0.06 m, has to be 'halved' to get the answer.

Also, 0.08 m along the direction of the wave is its wavelength.
