(a) An X-ray tube produces a continuous spectrum of radiation with its short wavelength end at 0.45 Å. What is the maximum energy of a photon in the radiation ? (b) From your answer to (a), guess what order of accelerating voltage (for electrons) is required in such a tube.  

Answer:

(a)                                                                                 (b)Since E = eV The order of accelerating voltage is
