WebInstead what we do is to use electrons. Since electrons have a rest mass, unlike photons, they have a de Broglie wavelength which is really short, around 0.01 nanometers for easily achievable speeds. This means that a microscope using electron "matter waves" instead of photon light waves can see much smaller things. 4 comments.
