The Young's double slit experiment is carried out with light of wavelength `5000Å`. The distance between the slits is `0.2 mm` and the screen is at `200 cm` from the slits. The central maximum is at `y=0`. The third maximum will be at `y` equal to

A

`1.67c`m

B

`1.5cm`

C

`0.5cm`

D

`5.0cm`

Text Solution

Verified by Experts

`X_(n)=(nlambdaD)/(d) or X_(3)=(3lambdaD)/(d)`
`x_(3)=(3xx(5000xx10^(-8))xx200)/(0.02) =1.5cm`
