The X-rays contains etc and these are the transitions between two atomic level . So
Also Hydrogen spectrum has quantized energy levels i.e and it contains so many  transitions between two energy levels like-Lyman, Balmer etc.  So
The photo electric effect is the emission of electron when photon incident on a metal. In beta minus decay, one neutron decay into a proton, an electron and an anti-neutrino.  So, So  
Mosley's law is an empirical law concerning the characteristic X-rays.  So
The Einstein's photoelectric equation is So
