Question

question 24
to answer the question, pay attention to what is circled in red.
what part of the wave is shown?
wavelength
amplitude
trough
crest

Explanation:

The amplitude of a wave is the maximum displacement from the rest position (equilibrium position) to the crest (or trough). In the given diagram, the red - circled part shows the distance from the rest position to the crest, which is the definition of amplitude. Wavelength is the distance between two consecutive crests (or troughs). Trough is the lowest point of the wave. Crest is the highest point of the wave.

Answer:

amplitude
