You are interested in investigating the atomic structure of a sample with a beam of electrons. The atomic structure has a characteristic size of 0.100 nm. Knowing that the observable detail of the atomic struture is limited to about the wavelength of the probe (electrons, in this case), to what speed should you accelerate the electrons in the beam? You may assume the electrons speed is non relativistic. Hint: de Brogile matter waves!
