QUESTION:

In an electron microscope, electrons are accelerated by passing them through a voltage difference. The kinetic energy thus acquired by the electrons is equal to the voltage times the charge on the electron. Thus, a voltage difference of 1 V imparts a kinetic energy of \(\mathrm {1.602 \times 10^{−19}~ C \times V ~or~ 1.602 \times 10^{−19}~ J}\). Calculate the wavelength associated with electrons accelerated by \(5.00 \times 10^3~ \mathrm V\).
