Principle of Superposition, Interference and Beats: Practice Problem & Solution
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: (2016 - II)
Solution Explained:
To solve this problem, we apply the core principles of Principle of Superposition, Interference and Beats. Understanding the underlying formula is key to arriving at the correct answer below:
The number of beats is determined by the maximum frequency difference among the superimposing waves. Max beat frequency = $(n+1) - (n-1) = 2$.
