Two points sources distance `0.1` m are viewed by a telescope. The objective is covered by ascreen having a hole of 1 mm widht. If the wavelenghts of light used is 5000Å, the the maximum distance at which the two sources are seen just resolved, will be

A

`125.0`

B

`102 m`

C

`131m`

D

`164 m`

Text Solution

Verified by Experts

The correct Answer is:
D
`(d)/(x)=(1.22lamda)/(D):.x=(10^(-3)xx10^(-1))/(1.22xx5xx10^(-7))=163.9m`
