Diameter of the objective lens of a telescope is 250 cm. for light of wavelength 600 nm. Coming from a distance object, the limit of resolution of the telescope is close to :

A

`1.5 xx 10^(-7)` rad

B

`2.0 xx 10^(-7)` rad

C

`4.5 xx 10^(-7)` rad

D

`3.0 xx 10^(-7)` rad

Text Solution

Verified by Experts

The correct Answer is:
D
Limit of resolution `= (122 lambda)/(d)`
`= (1.22 xx 600 xx 10^(-9))/(250 xx 10^(-2)) = 2.9 xx 10^(-7)` rad
