Question

wave properties review
directions: answer the question about amplitude.
the distance from the trough to the crest of a wave is 7 centimeters. what is the amplitude of the wave?
blank centimeters

Explanation:

Step1: Recall amplitude definition

Amplitude (\(A\)) is the distance from the rest position to a crest (or trough). The distance from trough to crest is \(2A\).

Step2: Calculate amplitude

Given trough - to - crest distance \(= 7\) cm, so \(2A=7\). Solve for \(A\): \(A = \frac{7}{2}=3.5\) cm.

Answer:

\(3.5\)
