What is the resolving power of a telescope whose objective lens has a diameter 1.22 m from a wavelength 4000 Å?

A

`2xx10^(6)`

B

`2.5xx10^(6)`

C

`2xx10^(5)`

D

`2.5xx10^(4)`

Text Solution

Verified by Experts

The correct Answer is:
B
`R.P.=(D)/(1.22lamda)`
`=(1.22)/(1.22xx4000xx10^(-10))=(10^(7))/(4)=2.5xx10^(6)`
