Three sound waves of equal amplitudes have frequencies (n-1) n (n+1). They superimpose to give beats. The number of beats produced per second will be 1 4 3 2
Multiple Choice Options
- A 1
- B 4
- C 3
- D 2
Step-by-Step Verified Solution
(n � 1) and (n + 1) suppose to form frequency n
n and n will be at resonance
n � 1 and n produce 1 beat
n + 1 and n produce 1 beat
_ Number of beats formed are �2�
