In a compound microscope, the distance between objective lens and eye lens is.

In a compound microscope, the focal length of the objective and the eye lens are 2.5 cm and 5 cm respectively. An object is placed at 3.75cm before the objective and image is formed at the least distance of distinct vision, then the distance between two lenses will be ( i.e. length of the microscope tube )

For a compound microscope, the focal length of object lens and eye lens are f_(o) and f_(e) respectively, then magnification will be done by microscope when

In a compound microscope, the objects is 1cm form the objective lens. The lenses are 30cm apart and the intermediate image is 5cm from the eye-piece. What magnification is produced?

In normal adjusment of telescope, final image is……. . And distance between objective lens and eye lens is………. .

In a compound microscope, the objective lens and……..are………. .

A compound microscope uses an objective lens of focal length 4 cm and eye lens of focal length 10 cm . An object is placed at 6 cm from the objective lens. Calculate magnifying power of compound microscope if final image is formed at the near point. Also, calculate length of the tube of compound microscope.

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

A convex lens of focal length f produces a real image 3 times as that of size of the object, the distance between the object and the lens is
