If the aperature of a telescope is decreased resolving power will

A

increases

B

decreases

C

remain same

D

zero

Text Solution

Verified by Experts

The correct Answer is:
B
(b) the resolving power of telescope = `a/(1.22lamda)`
where, a= aperature of telescope
`therefore` Resolving power `prop` aperature of telescope
If aperature of telescope is decreased, then the resolving power will decrease.
