हिन्दीThree 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
Correct answer · Option A
2
Explanation
The beat frequency is the difference between adjacent frequencies: \( (n) - (n-1) = 1 \) and \( (n+1) - n = 1 \). The maximum beat frequency among the combination is \( (n+1) - (n-1) = 2 \).
