Which of the following describes an instance of destructive interference?

Question

Group of answer choices

when circular waves become straight waves

when the waves' amplitudes do not change

when two crests overlap

when a crest and a trough overlap

Answer 1

Destructive interference occurs when a crest of one wave overlaps with a trough of another wave, resulting in a reduction or cancellation of the amplitude of the resultant wave. Therefore, the correct choice that describes an instance of destructive interference is:

when a crest and a trough overlap.
