An electron of mass m and charge e initially at rest gets accelerated by a constant electric field E.The rate of change of de broglie wavelength of this electron is |
|
Answer» Answer: around 0.01 NANOMETERS 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. |
