Question: X rays are produced in an x-ray tube by electrons accelerated through an electric potential difference of 50.0 kV. Let K0 be the kinetic energy

X rays are produced in an x-ray tube by electrons accelerated through an electric potential difference of 50.0 kV. Let K0 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 K1 = 0.500K0.
(a) What wavelength is associated with the photon that is emitted? The electron collides with another target nucleus (assume it, too, remains stationary) and then has kinetic energy K2 = 0.500K1.
(b) What wavelength is associated with the photon that is emitted?
