Beat Frequency
Beat is a word linked to sound waves. The beat frequency is not anything but the difference in frequency of two wave. It is because of the constructive and destructive interferences.
The formula for the beat frequency is,
\[f_{b}\, =\, \mid f_{2}-f_{1}\mid \]
Where the frequency of two waves are f1 and f2 .
let value of f2 = Y and f1 = X
