What is the relation between magnifying power and resolving power of a telescope ?

Text Solution

Verified by Experts

Magnifying power of a telescope is defined as the ratio of angle `beta` subtended at the eye by the final image, as seen through the telescope to the angle `alpha` subtended at the eye by the object, as seen directly.
Resolving power of a telescope is its power to see separately, the images of two stars with small angular separation. Resolving power of telescope is reciprocal of angular separation of two stars, which can just be seen as separate through the telescope.
