A telescope has an objective lens of `10 cm` diameter and is situated at a distance of one kilometer feom two ovjects. The minimum dustance between these two objects. Which can be resolved by the telescope, when the mean wavelength of light is `5000 Å,` is of the order of

A

0.5 m

B

5m

C

5mm

D

5 cm

Text Solution

Verified by Experts

`x/(1 times 10^-3)=(1.22 times 5000 times 10^-10)/(10 times 10^-12)= implies x=6mm`
