MHT CET 2026 Physics question

The beats are produced when there is a superposition of two sound waves which will have

(A)same amplitude and same frequency.
(B)different amplitude but same frequency.
(C)same amplitude but slightly different frequencies.Correct
(D)different amplitude and different frequencies.

Answer: (C)

Solution

Beats are the periodic waxing and waning of loudness heard when two sound waves of nearly equal (slightly different) frequencies, and , superpose; the beat frequency is . For well-defined beats (intensity falling to zero) the amplitudes should
