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

`10^(6)rad`

`10^(-2)rad`

`10^(-4)` rad

`10^(-6)` rad

Text Solution

Verified by Experts

The correct Answer is:

Angular resolution `d_(theta)=(1.22lambda)/(a)`
`=(1.22xx500xx10xx10^(-10))/(10xx10^(-2))=6.1xx10^(-6)rad.`
