(A)Frequency of beat changes with time
(B)Frequency of beat changes with location of observer.
(C)All the particles of medium vibrates simple harmonically with frequency equal to the. difference between the frequencies of component waves.
(D)Amplitude variation of particles at any point changes simple harmonically with frequency difference between two component waves.Correct

Answer: (D)

Solution

The beat frequency is constant in time and the same at every location, and particles vibrate with the mean frequency (not the
