Question

If a transverse wave measures 2 meters from peak to trough, what is the amplitude of the wave?

Answer 1

In waves, the amplitude (A) is defined as the distance between the origin to the peak or from the origin to the trough.

Then, From a peak to trough, there is two amplitudes

In our problem,

`2 A = 2 m\\ A=(2)/(2) =1m`

Then the amplitude of the wave is 1 meter
