What is the phase difference when two waves,traveling in the same medium,undergo constructive interference?
A)270 $\degree$
B)180 $\degree$
C)90 $\degree$
D)0 $\degree$

Question

Quizplus · Accepted Answer

Constructive interference occurs when two waves have the same frequency and amplitude and are in phase with each other. This means that the crests of the waves line up with each other, as well as the troughs. When this happens, the phase difference between the waves is 0 degrees. Therefore, choice D is the correct answer.
