Change in angular momentum of the electron in H-atom when it is excited from 2 nd orbit to 4 th orbit is given as
∆L=L2−L1- (a) Change in angular momentum of the electron in H-atom when it is excited from 2 nd orbit to 4 th orbit is given as
∆L=L2−L1
Where, L2 is angular momentum of 4 th excited state (n=5) and L is angular moment of 2 nd excited state (n=3).
∴∆L‌=‌
