Mosley measured the frequency (f) of the characteristic X - rays from many metals of different atomic number (Z) and represented his results by a relation known as Mosley's law. This law is ( a , b are constants )

Characteristic X-rays of frequency 4.2xx10^18 Hz are produced when transitions from L-shell to K-shell take place in a cartain target meterial. Use Mosley's law to determine the atoic number of the target matderial. Given Rydberg constant R =1.1xx10^7 m^(-1) .

According to Mosley's law, the frequency of a spectral line in X-ray spectru varies as

Some laws/processes are given in Column I. Match these with the physical phenomena given in Column II and indicate your answer by darkening appropriate bubbles in the 4 xx 4 matrix given in the ORS. {:("Column I","Column II"),((A)"Transition between two atomic energy levels",(P)"Characteristic X-rays"),((B)"Electron emission from a material",(Q)"Photoelectric effect"),((C )"Mosley’s law",(R )"Hydrogenspectrum"),((D) "Change of photon energy into kinetic energy of electrons",(S)beta-"decay"):}

In Moseley's law sqrt(v)=a(z-b), the volue of the screening constant for K-series and L-series of X-rays are respectively

In Mosley's equation , sqrtv = a(Z-b) which was derived from the observations made during the bombardment of the metal target with X - rays
