Question

Consider a metal used to produced some charateristic X-rays. Energy of X-rays are given by E and wavelength as represented by λ. Then which of the following is true :

Options

A.E(Kα) > E(Kβ) > E(Kγ)   
B.E(Mα) > E(Lα) > E(Kα)   
C.λ(Kα) > λ(Kb) > λ(Kγ)
D.λ32 = λ12 + λ22

Solution

Kα : transition from  2 → 1
Similarly for Kβ : 3 → 1 , Kγ : 4 → 1 ; Lα : 3 → 2 : Mα : 4 → 3
Now we can compare energy and λ .
