Question

Define resolving power of a telescope write the factors on which ot depends

Answer 1

The resolving power of a telescope depends on the diameter of the telescope's light-gathering apparatus, or objective. In a refracting telescope, the objective lens is the first lens the light passes through. In a reflecting telescope, the objective is the telescope's primary mirror.

Answer 2

Resolving power of a telescope:

• Resolving power of a telescope is the "reciprocal of the smallest angle" that can be subtended at the "objective lens" of telescope by the "two point objects" that can be just distinguished by separation.

• Normal working of a telescope depends on the amount of light that is being gathered into the apparatus which can be studied or which can be seen through the telescope.
• And it depends on the diameter of the telescope's light-gathering apparatus, or objective.
• So, the primary mirror in the telescope that is reflecting in nature and can be the Lens of telescope that has the refracting properties.
