Question

Let λ α , λ β and λ α ′ denote the wavelengths of the X-rays of the K α , K β and L α lines in the characteristic X-rays for a metal. Then,, 1 λ β = 1 λ α + 1 λ α ′, 1 λ ' α = 1 λ β + 1 λ α, 1 λ α = 1 λ β + 1 λ ' α, λ α = λ β + λ ' α

E L − E K = hc λ α ...(i) E M − E K = hc λ β ...(ii) E M − E L = hc λ α ' ...(iii) ( ii ) − ( i ) ⇒ E M − E L = hc λ α ' = hc λ β − hc λ α 1 λ β = 1 λ α + 1 λ α '
