2

A microscope that magnifies objects from 4x to 80x to investigate much larger objects, also called dissecting microscopes

3

A microscope which utilizes a beam of electrons that travel in shorter wavelengths than those of photons in visible light

volume_mute

Correct Answer:

transmission electron microscope

Explanation

These electrons are passed through a thinly sliced specimen within a vacuum to prevent any electrons from being deflected and absorbed by the gas molecules in the air.  Then the electrons are focused with electromagnets on a photographic plate, producing an image that is considerably better than that obtained with a light microscope.

4

A microscope which focuses electrons that bounce off the specimen

volume_mute

Correct Answer:

scanning electron microscope

Explanation

Then in the 1950s the scanning electron microscope (SEM) was invented, which focuses electrons that bounce off the specimen. Since the SEM has less resolving power than the transmission electron microscope, it doesn’t require a vacuum and allows researchers to view some smaller organisms alive
