There are two basic types of microscopes. They differ on the source of energy they use for imaging samples. A light microscope uses visible radiation (light from a light bulb) and the magnification power of multiple lenses to view samples all the way down to the cellular level. An electron microscope utilizes a beam of electrons as an energy source. Since the electrons have a much higher energy level than visible light, an electron microscope can be utilized to view much smaller objects than a light microscope. You can look at the detail of organelles, bacteria, and viruses. So the answer to the first two parts would be a light microscope while the answer to part 3 would be an electron microscope.
Light microscope has the ability to view samples down the cellular level as it contains multiple lens power and extraordinary light.
Electron microscopes consists of electron beams as its source of energy that can make easy for really small objects to be studied.
