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

`7.32 xx 10^(-6)` rad

B

`1.36 xx 10^(6)` rad

C

`7.32 xx 10^(-5)` rad

D

`1.36 xx 10^(5)` rad

Text Solution

Verified by Experts

The correct Answer is:
D
Resoving power = `(d)/(1.22 lambda) = (0.1)/(1.22 xx 6000 xx 10^(-10)) `
`1.36 xx 10^(5) ` radian.
