If two identical waves with a phase difference of 6π are added, the result is
A) a wave with the same frequency but twice the amplitude.
B) a wave with the same amplitude but twice the frequency.
C) a wave with zero amplitude.
D) a wave with zero frequency.
E) This problem cannot be solved without knowing the wavelengths of the two waves.

Quizplus · Accepted Answer

A phase difference of 6π is equivalent to a full cycle (2π) repeated three times, meaning the waves are in phase and will constructively interfere, resulting in a wave with the same frequency but twice the amplitude.
