Assuming that the resolution of an electron microscope is equal to the deBroglie wavelength of the electrons used, what is the resolution of an electron microscope (in nm) when the electrons are accelerated to a speed of (5.60x10^5) m/s?

Answer 1

wavelength = h/mv
Substitute for h and m and v. h is 6.626E034 J.s, m is 9.11E-31 kg, v is given in the problem. Solve for wavelength in meters. Then convert to nm.
