X rays are produced in an x-ray tube by electrons accelerated through an electric potential difference of 50.0 kV. Let K_(0) be the kinetic energy of an electron at the end of the acceleration. The electron collides with a target nucleus (assume the nucleus remains stationary) and then has kinetic energy K_(1)=0.500K_(0). (a) What wavelength is associated with the photon that is emitted? The electron collides with another target nucleus (assume it, too, remain stationary) and then has kinetic energy K_(2)=0.500K_(1). (b) What wavelength is associated with the photon that is emitted?
