In Young's doble slite experiment, the distance between the slit . The slite is illuminated by light of wavelenght `5000Å`. The third maximum will be at

A

`1.67 cm`

B

`1.5 cm`

C

`0.5 cm`

D

`5.0 cm`

Text Solution

Verified by Experts

The correct Answer is:
B
`x_(n)=(D)/(d) n lambda`
`:x_(3)=(D)/(d) 3 lambda=(3xx 3xx 5xx10^(-7))/(2xx10^(-4))=1.5 cm`
