In an electron microscope, we wish to study particles of diameter about 0.10 μm (about 1000 times the size of a single atom). (a) What should be the de Broglie wave- length of the electrons? (b) Through what potential dif- ference should the electrons be accelerated to have that de Broglie wavelength?
