Draw a ray diagram of compound microscope for the final image formed at least distance of distinct vision?

In a compound microscope, the intermediate image is

A compound microscope consists of two convex lenses having a focal length of $1.5 \mathrm{cm}$ and $5 \mathrm{cm}$. When an object is kept at a distance of $1.6 \mathrm{cm}$ from the objective, the final image is virtual and lies at a distance of $25 \mathrm{cm}$ from the eyepiece. Calculate magnifying power of the compound microscope in this setup.

Explain construction and working of compound microscope with diagram and find expression for its magnifying power when final image is formed at least distance of distinct vision.

Write the uses of electron microscope.
