A) 3
B) 1
C) 4
D) 2
Correct Answer: C
Solution :
We know that intensity \[l\propto {{a}^{2}},\]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.
