A K shell electron is ejected from a tungsten atom. The result of this is the emission of a characteristic x-ray proton. (The binding energy of the K shell in tungsten is 69.5keV. The binding energy of the L shell in a tungsten atoms is 10.5 keV).
a) If the vacancy in the K shell is filled by an electron from the L shell, what will the energy of the characteristic x-ray be?
b)If the K shell vacancy was filled by an electron from the M shell, would the enregy by higher or lower than the enregy from part a?
c)Why is this type of radiation called characteristic radiation?
The Attempt at a Solution
I got part a and b but can't get part c.
