If the intensity of light in double slit...

If the intensity of light in double slit experiment from slit 1 and slit 2 are `l_(0)` and `25l_(0)` respectively, find the ratio of intensities of light at minima and maxima in the interference pattern.

A

0

B

`(4)/(9)`

C

`(24)/(26)`

D

`(4)/(6)`

Text Solution

Verified by Experts

The correct Answer is:
B
At minima, `I="("sqrt(I_(0))-sqrt(25I_(0))")"^(2)=16I_(0)`
At maxima, `I="("sqrt(I_(0))+sqrt(25I_(0))")"^(2)=36I_(0)" ":." Ratio"=(16)/(36)=(4)/(9)`
