Scope- means “to look at”

Simple microscope- has only one lens
Compound microscope - has two or more lenses. Using two lenses makes things look larger rather than using one lens.

6. History of a microscope:
The first compound microscope was invented by Hans and Zacharias Janseen in 1590 in Denmark. Since then, many scientists and people used a microscope. Microscopes that we use in the classroom are called compound light microscopes.
