Q. The beats are produced by two sound sources of same amplitude and of nearly equal frequencies. The maximum intensity of beats will be … that of one source
A) Same
B) Double
C) Four times
D) Eight times
Explanation
(c) Intensity $\propto (amplitude)^{2}$
As $A_{\max} = 2a_{o}(a_{o} =$ amplitude of one source) so $I_{\max} = 4I_{o}$
