Question

What happens if two sound
waves having the same frequency interfere in phase

Answer 1

the amplitude of the resultant wave is greater than the amplitude of either of the two individual waves.

Answer 2

Constructive interference occurs and a new wave with a greater amplitude will be produced.

Step-by-step explanation:

Superposition of the two waves will occur and this will result in constructive interference.

Since the two waves have identical frequencies and they add, the constructive interference will produce a wave that will have a greater amplitude than the individual waves.
