If the ratio of magnifications produced by a simple microscope in near point adjustment and far point adjustment is 6/5, then the focal length of the lens is: (take D = 25 cm) If the ratio of magnifications produced by a simple microscope in near point adjustment and far point adjustment is 6/5 then the [...]

The objective of a compound microscope is essentially The objective of a compound microscope is essentially November 9, 2020 Category: Chapter 9 - Ray Optics , MTG NEET Physics , Part 1 ,

A compound microscope has an eye piece of focal length 10 cm and an objective of focal length 4 cm. The magnification, if an object is kept at a distance of 5 cm from the objective and final image is formed at the least distance of distinct vision (20 cm), is: A compound microscope has [...]

An astronomical telescope has an angular magnification of magnitude 5 for distant object. The separation between the objective and the eye-piece is 36 cm. The final image is formed at infinity. The focal length f0 of the objective and fe , of the eye-piece are : A ray of light is incident normally on one [...]

When a telescope is in normal adjustment, the distance of the objective from the eyepiece is found to be 100 cm. If the magnifying power of the telescope, at normal adjustment, is 24, the focal lengths of the lenses are: at normal adjustment is 24 the distance of the objective from the eyepiece is found [...]
