It is desired to produce x-ray radiation with a wavelength of 1 A. (a) Through what potential voltage difference must the electron be accelerated in vacuum so that it can, upon colliding with a target, generate such a photon? (Assume that all of the elec- tron's energy is transferred to the photon.) (b) What is the de Broglie wavelength of the electron in part (a) just before it hits the target?
