If two light waves having the same frequency have intensity ratio `4:1` and they interfere, the ratio of maximum to minimum intensity in the pattern will be

A

(a) `9:1`

B

(b) `3:1`

C

(c) `25:9`

D

(d) `16:25`

Text Solution

Verified by Experts

The correct Answer is:
A
`(I_(max))/(I_(min))=((sqrt(I_1/I_2)+1)/(sqrt(I_1/I_2)-1))^2=((sqrt(4/1)+1)/(sqrt(4/1)-1))^2=9/1`
