Homework Statement
What are the energies of the characteristic Kα line and Kβ lines?
Homework Equations
K-shell ( n =1):-69.5 keV
L-shell ( n =2 ): -11.3 keV
M-shell ( n =3 ): -2.30 keV
Z = 74
E = (energy level) (Z-1)2/n2
The Attempt at a Solution
for alpha i have
(-11.3keV) (74-1)2/22 for n =2
i know to find the energy characteristic i need to go from n=1 to n=2. so i know E = E1-E2
but for n=1 do use the energy level of the Kshell or the energy level of the Lshell?
in the lecture notes the instructed used the same energy level but didnt specify which one.
