An advantage of electron microscopes compared to light microscopes is that electron microscopes 1. are inexpensive and commonly used in most biology laboratories 2. allow you to view living cells, while light microscopes do not 3. have higher resolution that allows you to view smaller specimens 4. allow you to view the true colors of the specimens being viewed

3 - They do not only have a higher resolution, but a higher magnification.

Thanks to the electron light beam that goes trough the specimen, you can view smaller things un more detail, where with light microscopes smaller things can't be viewed that well, and detail is not as good.
