X-rays are produced by striking a target with a beam of electrons. Prior to striking the target, the electrons are accelerated by an electric field, increasing their potential energy by , where is the charge of an electron and is the voltage of the electric field. If volts, what is the minimum wavelength of the emitted radiation?
