If the aperature of a telescope is decreased resolving power will

A

increases

B

does not change

C

becomes infinity

D

decreases

Text Solution

Verified by Experts

The correct Answer is:
D
For a telescope, R.P. `(D)/(1.22lamda)`
If the aperture (diameter) of the objective of a telescope is decreased then its resolving power is decreased.
