What happens to the amplitude of the resultant wave when two sound waves with equal amplitude constructively interfere? a. it is half than the amplitude of each wave. b. it is twice than the amplitude of each wave. c. it is the mean of the amplitudes of the two waves. d. it is the square of the amplitude of each wave. e. it is zero.

Respuesta :

The amplitude of the resultant wave when two sound waves with equal amplitude constructively interfere, will be twice than the amplitude of each wave.

What is a constructive interference?

A constructive interference occurs when two sound waves with equal amplitude moving in the same direction collide which each other, forming a single wave (resultant wave) with a higher amplitude.

Thus, we can conclude that the amplitude of the resultant wave when two sound waves with equal amplitude constructively interfere, will be twice than the amplitude of each wave.
