Summary Introduction
Introduction:
The microscope becomes effective with three properties. These properties are: contrast, resolution, and magnification. Magnification is the increase in the size of an object under microscope to make it clearly visible. Magnification is the result of refraction of light beam or electron beam when it passes through a lens.

Of the four major types of microscopes, give an example of a scenario in which each
would be the ideal choice for visualizing a sample.
Stereo (Dissecting)
Compound
Confocal
Electron
In light microscopy, when magnification is increased, the lens focuses closer to the sample. This makes the user more likely to ram the sample into the lens.
Why is it common for the lens to focus closer to the sample at higher magnifications? What can be done to mitigate this risk?
The most widely used type of light microscope is the
