In Young's Double slit experiment, a thin glass mica strip of thickness `(t=8lamda)` is pasted infront of slit `S_(1)`. If the same strip is now shifted in front of other slit `S_(2)`. If the number of fringes which will cross the central point on the screen in `N`. Find `N`? `(dgt gtlamdad` and `n_(mica)=1.5)`

Text Solution

Verified by Experts

The correct Answer is:
8
`(mu-1)t=nlamda`
`n-` number of fringes shifted
`(1.5-1)8lamda=nlamda`
`n=4`
Total number of finges shifted
`=8`
