What is the main difference between an electron microscope and an optical microscope?


a) Electron microscopes use electrons instead of photons or visible light to form images.
b) Electron microscopes have a higher resolution power than optical microscopes.
c) Electron microscopes have a maximum capacity to show image details when the distance between them is approximately 0.2 micrometers.
d) Electron microscopes were first designed by Ernst Ruska and Max Knoll between 1925 and 1932.
e) Electron microscopes are commonly used in the study of integrated circuits.
