Draw a schematic ray diagram of a compound microscope with the final image formed at infinity.

Define the magnifying power of a compound microscope when the final image is formed at infinity. Why must both the objective and the eyepiece of a compound microscope have short focal lengths ? Explain.

Draw a labelled ray diagram of an image formed by a compound microscope with final image formed at the least distance of distinct vision (D). Derive an expression for its magnifying power (in terms of V_(0), U_(0),f_(c) and D).

In a compound microscope, the intermediate image is

Draw a labelled ray diagram of an image formed by a refracting telescope with final image formed at infinity. Derive an expression for its magnifying power with the final image at infinity

Draw a labelled ray diagram of an image formed by a compound microscope, when the final image lies at the least distance of distinct vision.

In Gallilean telescope, the final image formed is

(i) Draw a neat labelled ray diagram of a compound microscope . Explain briefly its working . (ii) Why must both the objective and the eye-piece of a compound microscope have short focal lengths ?

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.

In a simple microscope, if the final image is located at infinity then its magnifying power is

Find the distance between the two lenses of a compound microscope if the final image formed by the microscope is virtual and lies at a distance of 25cm to the left of the eye- piece. Magnifying power of the microscope is 30 and focal lengths of objective and eyepiece are 2cm and 5cm, respectively.
