The minimum magnifying power of an astronomical telescope is M. If the focal length of its eye-lens is halved, the minimum magnifying power will become:

A

M/2

B

2M

C

3M

D

4M

Text Solution

Verified by Experts

The correct Answer is:
B
`MP=-((f_(0))/(f_(theta)))`
If we use a eyepiece of focal length halved, then MP become double.
