The diameter of the objective of the te...

The diameter of the objective of the telescope is `0.1` metre and wavelength of light is `6000 Å`. Its resolving power would be approximately

A

`7.32xx10^(-6)rad`

B

`1.36xx10^(6)rad`

C

`7.32xx10^(-5)rad`

D

`1.36xx10^(5)rad`

Text Solution

Verified by Experts

The correct Answer is:
D
Resolving power `=(d)/(1.22lambda)=(0.1)/(1.22xx6000xx10^(-10))`
`~= 1.36xx10^(5)radian`
