If the amplitude of the resultant wave is twice as great as the amplitude of either component wave, and this wave exhibits reinforcement, the component waves must
This question seems to really be incomplete. You must include the options but fortunately I have already encountered this problem. Here are the choices:
A. have a different frequency than the resultant wave. B. be in phase with each other. C. be traveling in the opposite direction of the resultant wave. D. have a different wavelength than the resultant wave
The correct answer is letter B. be in phase with each other
If the amplitude of the resultant wave is twice as great as the amplitude of either component wave, and this wave exhibits reinforcement, the component waves must BE IN PHASE WITH EACH OTHER
