The aperture of the objective of a telescope is 0.1 m and wavelenth of light is 6000 Å. The resolving limit of the telescope will approximately be _________ .

A

`6xx10^(-5)` rad.

B

`6xx10^(-4)` rad.

C

`6xx 10^(-3)` rad

D

`6xx10^(-6)` rad

Text Solution

Verified by Experts

The correct Answer is:
D
Resolving limit ` (lambda)/(dlambda)= (1.22lambda)/(D)`
=`(1.22xx6000xx10^(-10))/(0.1)`
`~~6xx10^(-6)` rad .
