The crest of one wave lines up with the trough of another wave. What happens between the waves?

A. A breaking wave

B. Destructive interference

C. Constructive interference

D. Wave reflection

Answer: Option B

Explanation: The peak of a wave can be called the "positive" part of the wave, and the trough part of a wave can be called the "negative" part of a wave.

So if these two parts of the wave interfere with each other, they cancel each other (because one is "positive" and the other "negative")

This effect is called Destructive Interference (in the case where two peaks or two troughs interfere, the phenomenon is called constructive interference)

Then the correct option is B

D

Explanation:

wave reflection I think is preferable
