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
Angular resolution `= (1.22lambda)/(a)`
`= (1.22xx5000xx10^(-10))/(10xx10^(-2)) = 6.1 xx 10^(-6)rad`
