Q. 14

Two coherent sour A. 25 : 1

B. 5 : 1

C. 9 : 4

D. 625 : 1

Answer :

Let the amplitude of two sources be and .

Now for maximum intensity, the resultant amplitude is

And for minimum intensity, the resultant amplitude is

and intensities are proportional to the amplitudes. Therefore, the maximum amplitude is

and minimum amplitude is

let

Now, the ratio of intensities is

solving this, we get . Hence, option (c) is the current answer.
