a wave of amplitude 0.31 m interferes with a second wave of amplitude 0.17 m traveling in the same direction. (a) what is the largest resultant amplitude that can occur, and under what conditions will this maximum arise? m the two waves interfere destructively. the two waves interfere constructively. (b) what is the smallest resultant amplitude that can occur, and under what conditions will this minimum arise? m the two waves interfere destructively. the two waves interfere constructively.
