Two sound waves are traveling through the same medium.They have the same amplitude, wavelength, and direction of travel.If the phase difference between them is 7π, the type of interference they exhibit is:
A)fully constructive
B)fully destructive
C)indeterminate
D)partially constructive
E)partially destructive

Question

Quizplus · Accepted Answer

A phase difference of 7π represents half a wavelength, plus an additional 3.5 wavelengths. This means that the two waves are perfectly out of phase, leading to complete destructive interference.
