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. (d) different amplitude and different frequencies.

Answer: (c). Beats need a small frequency difference; equal frequencies give no beats Equal amplitudes make the minima zero, so the beats are clearest So the answer is (c) same amplitude but slightly different frequencies.
