Question

Write an expression for the magnifying power of a simple microscope. How can it be increased?

Answer 1

The magnifying power of the microscope is given as
Magnifying power M = 1 + D / f
Where f is the focal length of the lens and D is the least distance of distinct vision
The magnifying power of the microscope be increased by using the lens of short focal length i.e shorter the focal length, more is the magnifying power. But it cannot be increased indefinitely.
