If two sound waves of frequencies \[\mathbf{500}\text{ }\mathbf{Hz}\] and \[\mathbf{550}\text{ }\mathbf{Hz}\] superpose, will they produce beats? Would you hear the beats?

Answer:

                Yes, the sound waves will produce 50 beats every second. But due to persistence of hearing, we would not be able to hear these beats. We would hear a continuous sound of frequency\[\text{5}0\text{ Hz}\], called beat tone.
