Question

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

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.

Answer 1

B. they would have to be in phase with each other.

Answer 2

Answer: 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 if this wave exhibits reinforcement, the component waves must be in phase with each other.e
