What can accurately be said about a resultant wave that displays both reinforcement and interference? a. the component waves have different frequencies. b. maximum interference occurs where the troughs of the two component waves are in phase. c. molecules remain in their normal positions at spots of reinforcement. d. the crests of the two component waves are in phase where interference occurs in the resultant wave. mark for review (will be highlighted on the review page)

The answer is A. The component waves have different frequencies.
The magnitudes of reinforcement usually really dependent on the number of frequencies and interference is usually caused due to the difference in frequencies. So, we can conclude that if the frequencies are different and causing interference, the reinforcement will also different

Answer;

A. The component waves have different frequencies.

Explanation;interference is one of the property of waves that occurs when  two waves superpose to form a resultant wave of greater, lower, or the same amplitude.Interference occurs when two waves travelling in the same medium at the same time. It may be either a constructive or a destructive interference.Constructive interference occurs when the two waves are in phase and have the same frequency, the amplitudes are therefore, reinforced resulting to a constructive interference. However, if the two waves are out phase the result will be a destructive interference.
