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
R.P. of a telescope`=(D)/(1.22lamda)`
thus, R.P. `prop(1)/(lamda)`
`therefore `R.P is increased when `lamda` is decreased.
