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?

Explanation

(a) 49.6 pm, (b) 99.2 pm
