The angular resolution of a `10cm` diameter telescope at a wavelength `5000Å` is of the order

A

`10^(6)` rad

B

`10^(-2)` rad

C

`10^(-4)` rad

D

`10^(-6)` rad

Text Solution

Verified by Experts

The correct Answer is:
D
Using , `d theta=(1.22lambda)/(D)=(1.22xx5000xx10^(-10))/(0.10)`
` " "=6.1xx10^(-6)"rad"=10^(-6)`rad
