A) 3
B) 1
C) 4
D) 2
Correct Answer: C
Solution :
We know that intensity \[I\propto {{a}^{2}}\] , where a is amplitude of the wave. The maximum amplitude is the sum of two amplitudes i.e., \[(a+a=2a)\] Hence, maximum intensity \[\propto 4{{a}^{2}}\] Therefore the required ratio i.e., ratio of maximum intensity (loudness) and intensity (loudness) of one wave is given by n, \[n=\frac{4{{a}^{2}}}{{{a}^{2}}}=4\]You need to login to perform this action.
