(choose chapter or problem)

In an X-ray tube (see Fig.  and discussion in Section  ), the high voltage between filament and target is . After being accelerated through this voltage, an electron strikes the target where it is decelerated (by positively charged nuclei) and in the process one or more X-ray photons are emitted. (a) Show that the photon of shortest wavelength will have

     \(\lambda_0=\frac{hc}{eV}\)

(b) What is the shortest wavelength of X-ray emitted when accelerated electrons strike the face of a 30-kV television picture tube?
