Choose the answer that is most correct about Light microscopes

• uses only two lenses to magnify an object

• can only view nonliving specimens

• can only view living specimens

• use light focused by two lenses to magnify images

Choose the answer that is most correct about Electron microscopes

• uses beams of electrons focused by a magnetic field to magnify image

• uses light to magnify image

• Uses light and two glass lenses to magnify image

• shows only one dimensional image of specimen

Microscopes that uses beams of electrons show a 2 dimensional image of a non-living specimen that is sliced extremely thin and placed in a vacuum is called (a)   .

Microscopes that use beams of electrons to make a 3 dimensional image of the surface of a specimen placed in a vacuum is called (a)   .
