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

Answer choices are:

A. be traveling in the opposite direction of the resultant wave.

B. have a different frequency than the resultant wave.

C. be in phase with each other.

D. have a different wavelength than the resultant wave.

Correct answer choice is:

C. Be in phase with each other.

Explanation:

Components waves mix to produce a resultant with the equivalent wavelength but the amplitude which is bigger than the amplitude of both of the unique component waves, and this results in constructive interference, which states that the interference of two or more waves of identical frequency and phase, constructing in their respective reinforcement and constructing a single amplitude equivalent to the total of the amplitudes of the unique waves.
