Question

What are beats? Prove that the number of beats per second is equal to the difference between the

frequencies of two superimposing waves.​

Answer 1

Answer:

The third maximum at t3 = 2/n1 – n2 and so on. Hence the number of beats produced per second is equal to the reciprocal of the time interval between two successive maxima. Hence, the number of beats produced per second is equal to the reciprocal of time interval between two successive superimposing waves.
