What happens when two frequencies collide?
Constructive interference describes what happens when sound waves that are of equal frequency and phase add together to form a wave of larger amplitude. … When sound waves of different frequencies collide, the result is beating because part of the wave interferes constructively and part interferes destructively.
How do you superposition waves?

The net displacement of the medium at any point in space or time, is simply the sum of the individual wave displacements.
