Assertion : The resolving power of a tel...

Assertion : The resolving power of a telescope is more if the diameter of the objective lens is more.
Reason : Objective lens of large diameter collectd more light.

A

If both, Assertion and Reason are true and the Reason is the correct explaination of the Assertion.

B

If both, Assertion and Reason are true but Reason is not a correct explaination of the Assertion.

C

If Assertion is true but the Reason is false.

D

If both, Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Both, the Assertion and Reason are true and latter explains the former correctly. As `R.P. = (D)/(1.22 lambda)`, where `D` is the diameter of the objective lens. Moreover, large objective lens collects more light and hence image becomes brighter.
