De broglie wavelength in terms of temperature
WebSince 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 ( 98 votes) Upvote Downvote Flag more Show more...
