consider an electron revolving around nucleus in a circular orbit

here the circumference is equal to whole number multiple of wavelength of electron waves

so

2 pie r=n lamda

lamda=2 pie r/n

from diebrog;ie concept

lamda=h/mv

therefore

h/mv=2 pie r/n

m.v.r=n.h/2 pie

hence its integral multiple of h/2 pie

v is velocity of electron,

r is the radii

angular momentum is n.h/2 pie

hence
