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

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

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.
