Define magnifying power and resolving power of a telescope.

What is meant by resolving power of a telescope ?

Define Magnifying Power of a simple astronomical telescope.

State any one method of increasing the resolving power of an astronomical telescope.

Define magnifying power of a microscope in terms of visual angle.

(i) Define magnifying power of a microscope in terms of visual angle. (ii) What is the advantage of a compound microscope over a simple microscope ?

Resolving power of a telescope increases with

Assertion (A) To increase resolving power of a telescope, the aperture (a) of the object should be large. Reason (R ) Resolving power of the telescope is given by (2a)/(1.22lambda) .

The minimum magnifying power of an astronomical telescope is M. If the focal length of its eye-lens is halved, the minimum magnifying power will become:

The minimum magnifying power of an astronomial telescope is M . If the focal length of its eye-lens is halved, how much times the minimum magnifying power will increase.

Diameter of the objective of a telescope is 200cm. What is the resolving power of a telescope? Take wavelength of light =5000Å.
