Electron microscopes use:

• Mirrors or lenses to direct the beam of electrons

• Magnets to direct the beam of electrons

• A colored stain

• Light

What is the difference between magnification and resolution?

• Magnification describes how blurry a larger image is

• Resolution describes how clear an image is, while magnification describes how much larger it is than normal

• Magnification refers to electron microscopes while resolution refers to light microscopes

• All microscopes have the same resolution, but different magnifications
