When two waves with the same amplitudes and if the same type that are perfectly in phase with each other continuously pass through each other and constructively interfere with each other is the intensity of the resultant wave 2 or 4x more than that of each of the original waves? 🙂

Update: nevermind, I was looking in the wrong part of the answers section 😂

Lol that apparently isn't correct because intensity is directly proportional to the amplitude of the wave squared 😄🙂

Using principle of superposition of waves, amplitude of resultant wave is twice that of an individual wave. Increases by factor 2.

Hence amplitude squared increases by a factor 4.

Intensity is proportional to amplitude squared.

So intensity must also increase by a factor of 4.
