Question
The energy of a tungsten atom with a vacancy in L shell is 11.3 KeV. Wavelength of Kα photon for tungsten is 21.3 pm. If a potential difference of 62 kV is applied across the X - rays tube following characteristic X - ray will be produced.
Options
A.K,L series
B.only Kα & L series
C.only series
D.None of thes
Solution
ᐃE = 
ᐃE2 = 58.21 keV ; ᐃE1 = 11.3 KeV ; ᐃE = 69.51 KeV
ᐃE < 62 KeV Therefore only L series will be produced
ᐃE2 = 58.21 keV ; ᐃE1 = 11.3 KeV ; ᐃE = 69.51 KeV
ᐃE < 62 KeV Therefore only L series will be produced
