Electrons with energy 80 keV are incident on the tungsten target of an X-ray tube. The K-shell electrons of tungsten have -72.5 keV energy. The X-rays emitted by the tube contains only
Options
(a) characteristic X-ray spectrum of tungsten
(b) a countinuous X-ray spectrum with all wavelengths
(c) a countinuous X-ray spectrum with a minimum wavelength of 0.155 Å
(d) a countinuous X-ray spectrum with a minimum wavelength of 0.155 Å and the characteeristic X-ray spectrum of tungsten
