Biologists and medical researchers commonly use electron microscopes instead of light microscopes when very fine detail is desired. This photo shows a colorized transmission electron micrograph of Clostridium butyricum bacteria, magnified approximately 50,000 times. Spores (orange) and granules (blue) are visible, surrounded by cytoplasm (yellow) within the cell. What enables an electron microscope to achieve a greater resolution than a light microscope? Are there any limits to the resolution of an electron microscope?
