Question

two waves overlap producing a new wave that exhibits destructive interference. which statement correctly describes the new wave? a. it has taller crests than the waves that overlapped to produce it. b. it has a larger amplitude than the waves that overlapped to produce it. c. it has a smaller amplitude than the waves that overlapped to produce it. d. it has deeper troughs than the waves that overlapped to produce it

Explanation:

Destructive interference occurs when two waves overlap. In this case, the crest of one wave aligns with the trough of the other. This causes their amplitudes to subtract. As a result, the new wave formed has a smaller amplitude than the original waves. Options A, B, and D suggest an increase in amplitude (taller crests, larger amplitude, deeper troughs), which is characteristic of constructive interference, not destructive.

Answer:

C. It has a smaller amplitude than the waves that overlapped to produce it.
