1. Electron beam can pass through thick materials, whereas light microscopy requires thin sections
2. The electron microscope is more powerful than the light microscope as it uses a beam of electrons which has wavelength much longer than that of photons
3. The resolution power of the electron microscope is much higher than that of the light microscope
4. The revolving power of the electron microscope is 200-350 nm as compared to 0.1 – 0.2 nm for the light microscope
The resolution power of the electron microscope is much higher than that of the light microscope
