What is the magnification produced in a plane mirror ?

An object is placed at a distance of 5 cm from the objective of a compound microscope . If the final image is formed at the least distance of distinct vision and coincides with the object then calculate the focal lengths of the objective and the eyepiece . given that the least distance of distinct vision =25 cm and the magnifying power of the instrument = 15 cm.

A figure divided into squares, each of size 1.0 mm^2 is being viewed at a distance of 9.0 cm through a magnifying lens of focal length 10 cm held close to the eye. (i) The magnification produced by the lens will be

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 has short focal lengths ? Explain.

The focal of the objective and the eyepiece of a compound microscope are 0.5 cm and 1 cm respectively . The distance between the lenses is 16 cm . If the final image is formed at the least distance of distinct vision i.e at 25 cm ,determine the magnifying power of the instrument .
