Define the magnifying power of a telescope.

The diameter of the objective lens of a telescope is 10 cm . Calculate the resolving power of the telescope for lambda=500 nm .

How can you determine the resolving power of your eye?

What steps can be taken to restore the river Ganga to its past glory?

Draw a labelled ray diagram of an astronomical telescope for the near point adjustment. You are given three lenses of power·0.5 D, 4 D, 10D. State with reason, which two lenses will you select for constructing a good astronomical telescope. Calculate the resolving power of this telescope, assuming the diameter of the objective lens to be 6 cm and the wavelength of light used to be 540 nm.

What is resolving power? Give an expression for resolving power of a telescope.
