Caprice · Answer 1

In physical science that deals with waves, if we say "constructive interference" we generate a wave that has an amplitude that is the sum of the amplitudes of two waves. Also, we say "destructive interference" when we generate a wave that has an amplitude that is the difference of the amplitudes of the two waves. In this number, the answer should therefore be any of the choices c and d.
