Question

State whether true or false :
During destructive interference, the crest of one wave meets the trough of the other wave.

• A. True
• B. False

Answer 1

The correct option is A True

When the crest of one wave meet the crest and trough of other wave, then we say that destructive interference between the waves takes place.
The amplitude of the resultant wave produced by destructive interference is minimum.
In case, if the two interfering waves have equal amplitude. Then, the amplitude of the resultant wave is zero.
