The objective lenses of two telescope ha...

The objective lenses of two telescope have the same apertures but their focal lengths are in the ration `1 : 2`. Compare the resolving powers of the two telescopes.

Text Solution

Verified by Experts

Resolving power of a Telescope `= (1.22 D)/(lamda)` as the apperture of telescope is same, so resolving power will not change.
