The maximum intensity of fringes in Youn...

The maximum intensity of fringes in Young's experiment is I. If one of the slit is closed, then the intensity at that place becomes `I_o`. Which of the following relation is true?

A

`I=I_(o)`

B

`I=2I_(o)`

C

`I=4I_(o)`

D

there is no relation between I and `I_(o)`

Text Solution

Verified by Experts

The correct Answer is:
C
If a is the amplitude of wave, then
`I=4a^(2),"then "I_(0)=a^(2)=I/4`.
