Question

directions: answer the question about amplitude.
the distance from the trough to the crest of a wave is 10 meters. what is the amplitude of the wave?
______ meters.

Explanation:

Step1: Recall amplitude definition

Amplitude ($A$) is the distance from the midline (equilibrium) to a crest or trough. The distance from trough to crest is $2A$.

Step2: Solve for amplitude

Given trough - to - crest distance is 10 m, so $2A = 10$. Divide both sides by 2: $A=\frac{10}{2}=5$.
