Question

A wave has an amplitude of 0.2 cm.

What does this mean?

Select one:

- The horizontal distance between a crest and a trough is 0.2 cm.

- The distance between the resting point and the maximum height of the wave is 0.2 cm.

- The distance between two crests is 0.2 cm.

- The vertical distance between a crest and a trough is 0.2 cm.

Answer 1

The distance between the resting point and maximum height of the wave is 0.2 cm.

The amplitude is measured from the resting point up to the highest point of the wave.
