Two waves overlap producing a new wave that exhibits destructive
interference will have a smaller amplitude than the waves that overlapped to
produce it.
Interference is a phenomenon which occurs when two waves travelling in
the same medium( which could be water, air etc) meet. There are two types
of interference namely:
The destructive interference involves the positive and negative
displacement canceling out which result in zero displacement or
amplitude.This fact validates option B which states that the new wave will
have smaller amplitude than the waves that overlapped to produce it.
