Define Magnifying Power of a simple astronomical telescope.

Define resolving power of a simple astronomical telescope. State one advantage of a reflecting telescope over refracting telescope.

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.

Magnifying power of an astronomical telescope is M.P. If the focal length of the eye-piece is doubled, then its magnifying power will become

The magnifying power of an astronomical telescope for normal adjustment is 10 and the length of the telescope is 110cm..Find the magnifying power of the telescope when the image is formed at the least distance of distinct vision for normal eye.

How will the magnifying power of an Astronomical telescope be affected on increasing (i) the focal length and (ii) the aperture of its objective

The magnifying power of an astronomical telescope for relaxed vision is 16 and the distance between the objective and eyelens is 34 cm. Then the focal length of objective and eyelens will be respectively

The magnifying power of an astronomical telescope is 8 and the distance between the two lenses is 54 cm. The focal length of eye lens and objective will be respectively.

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

The magnifytion power of the astronomical telescope for normal adjustment is 50cm. The focal length of the eyepiece is 2cm. The required length of the telescope for normal adjustment is
