The magnifying power of a telescope in normal adjustment is greater than that when it is focussed for least distance ofdistinct vision. Is this true or false? Give reasons.

The magnifying power of a simple microscope is 6. The focal length of its lens in metres will be, if least distance of distinct vision is 25cm

Magifying power of a telescop in normal adjustment when final images of a star is formed at inifnity is 9. the image of a star is formed at inf

The magnifying power of simple microscope is 6 when the image is formed at distance of distinct vision (25 cm) from its optical centre. The focal power of the simple microscope in dipotre is

Magnification produced by astronominal telescope for normal adjustment is 10 and length of telescope is 1.1m. The magnification when the image is formed at least distance of distinct vision (D = 25cm) is-

A small telescope has an objective lens of focal length 140 cm and eye piece of focal length 5.0 cm . What is the magnifying power of telescope for viewing distant objects when (a) the telescope is in normal adjustment (i.e. when the image is at infinity) (b) the final image is formed at the least distance of distinct vision (25 cm) .
