Question

jeremiah is studying wave a and wave b. wave a is traveling at 3 hertz, and wave b is traveling at 1.2 hertz. what can be predicted about the waves if they were to crash into each other? retraction would occur. interference would occur. the resulting wave would travel at 4.2 hertz. the crest of wave a would overlap the trough of wave b.

Explanation:

When two waves meet, interference occurs. Refraction is about wave - bending when passing through different media. The frequency of the resulting wave in interference is not simply the sum of the frequencies of the original waves. There is no information to suggest a specific crest - trough overlap.

Answer:

Interference would occur.
