The resolving power of a telescope whose lens has a diameter of 1.22 m for a wavelength of `5000 Å` is

A

`2xx10^(5)`

B

`2xx10^(6)`

C

`2xx10^(2)`

D

`2xx10^(4)`

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Resolving power of telescope =`d/(1.22lamda)=1.22/(1.22xx500xx10^(-10))`
`=2xx10^(6)`
