Two coherent sources have intensity in the ratio of `(100)/(1)`. Ratio of (intensity) max/(intensity) min is

Options

A. (a) `(1)/(100)`
B. (b) `(1)/(10)`
C. (c) `(10)/(1)`
D. (d) `3/2`

Answer

D

Explanation

`I_1/I_2=(100)/(1)`
Now `(I_(max))/(I_(min))=((sqrt(I_1/I_2)+1)/(sqrt(I_1/I_2)-1))^2=((sqrt100+1)/(sqrt100-1))^2=(121)/(81)~~3/2`
