Two different wave groups with the same height travel together in the same direction. The wavelength of one group is twice as long as the wavelength of the other group. A combined wave of extra height will be produced
A) every wave.
B) every other wave.
C) every third wave.
D) every fifth wave.
E) every seventh wave.

Question

Quizplus · Accepted Answer

The combined wave of extra height occurs when the peaks of both wave groups align, which happens every other wave due to the difference in wavelength (one being twice as long as the other).
