Below you see a diagram of three waves.
The top wave oscillates exactly 10 times in the time interval shown. However the one underneath it is vibrating slightly faster, completing exactly 12 oscillations in the same amount of time.
The third diagram shows the sum of the two waves. As you can see, there are times when the two waves are in phase with each other, causing maximum constructive interference. There are also two times when they are 180 degrees out of phase causing maximum destructive interference.
Below is an animation of how that would evolve in time.
Before proceeding, consider the following question: If your ear were to the right, how would that sound to you? Predict what you would hear.
To test your prediction, do the following experiment ....
