The image formed by an objective lens of a compound microscope is

$A$ thin convex lens of focal length $5 \, cm$ is used as a simple microscope by a person with a normal near point of $25 \, cm$. What is the magnifying power of the microscope?

What is a compound microscope? Explain its construction with the help of a figure.

The objective of a compound microscope is essentially

In a compound microscope,cross-wires are fixed at the point:

$A$ compound microscope with an objective lens of focal length $1 \, cm$ and an eyepiece of $2 \, cm$ focal length has a tube length of $20 \, cm$. Calculate the magnifying power of the microscope,if the final image is formed at the least distance of distinct vision.
