Infinity Learn · Accepted Answer

Minimum wavelength of continuous $$X-ray$$ spectrum is given by λminin  $$Ao=12375EeV=1237580$$×$$103$$≈$$0.155$$ Also the energy of the incident electrons (80$$ K $$eV) is more than the ionization energy of the $$K-shell$$ electrons (i$$.e., $$72.5$$ K $$eV). Therefore $$characteristicX-ray$$ spectrum will also be obtained because energy of incident electron is enough to knock out the electron from K or L shells.
