Two sounds of equal intensity I generates beats. The max. intensity of sound produced in beats will be:

A)I

B)2I

C)4I

D)I/2

Thanks!!

Dear Prajwal kr

intensity max= ((I₁)^1/2+(I₂)^1/2)²  AS I1=I2

therfore by the realtion we get (I+I)²=4I

C)IS CORRECT..!!!

Thnks..!!

I'' =  root(I1^2) + root(I2^2) +2root(I1)root(I2)cos @
   =root(I^2) + root(I^2)
   =2I 

Please approve :) 

One very important fact

two non coherent sources will never give a clear interference pattern

hence you only talk about the average of them

maxium = minimum = I + I = 2I

always...
