Resolving power of telescope increases when

A

wavelength of light decreases

B

wavelength of light increases

C

focal length of eye-piece increases

D

focal length of eye-piece decreases

Text Solution

Verified by Experts

The correct Answer is:
A
Resolving power of a telescope is given by
`RP=d/(1.22lambda`
i.e. `RP prop1/lambda`
When lambda (wavelength of light) decreases, resolving power of a telescope increases.
