Define magnifying power and resolving power of a telescope.

A: The resolving power of a telescope decreases on decreasing the aperture of its objective lens. R: The resolving power of a telescope is given as D/(1.22 lamda) where D is aperture of the objective and lamda is the wavelength of light.

Assertion : The resolving power of a telescope is more if the diameter of the objective lens is more. Reason : Objective lens of large diameter collectd more light.
