Question

choose the correct answer.
is \a\ or \b\
measuring
amplitude?
a
b

Explanation:

Step1: Recall the definition of amplitude

Amplitude is the maximum displacement from the equilibrium position (in a wave, it's the distance from the mid - line to a crest or trough).

Step2: Analyze the given diagram

In the diagram, label A is measuring the distance between two crests (which is the wavelength). Label B is measuring the distance from the mid - line (equilibrium position) to a point on the wave, which fits the definition of amplitude.

Answer:

B
