Two sound waves of the same frequency can interfere with each other, but two sound waves must have different frequencies in order to make beats. Discuss the reason for this.
Answer & Explanation
We can assume that when the two waves are of the same frequency that they would produce either constructive or destructive interference, so beats can not be made this way because they are either in step of out of it. So if we have two different frequencies, we can assume that they would be constantly changing from phase to out of phase and so on, which would make the sound increase and decrease, and increase and so on.
