Question

if the distance between the crest and trough of a wave is 1.2 m, the waves amplitude is
0.6 m
1.2 m
2.4 m
4.8 m

Explanation:

Step1: Recall wave - amplitude concept

The distance from the crest to the trough of a wave is equal to \(2A\), where \(A\) is the amplitude of the wave.

Step2: Solve for amplitude

Given \(2A = 1.2\ m\), then \(A=\frac{1.2}{2}\ m\).

Answer:

A. \(0.6\ m\)
