Question

what is the amplitude of the transverse wave modeled in the following figure if the height of a crest is 3 cm above the resting position of the medium? a 8 cm b 3 cm c 2 cm d 5 cm

Explanation:

Step1: Recall Amplitude Definition

Amplitude of a transverse wave is the maximum displacement of a point on the wave from its resting (equilibrium) position.

Step2: Apply to Given Problem

The crest is 3 cm above the resting position. By definition, this maximum displacement (amplitude) is equal to the height of the crest above the equilibrium. So amplitude = 3 cm.

Answer:

b. 3 cm
