Derivation of Bohr's postulates of quantisation of angular momentum from de Broglie equation.
Thus the angular momentum (mvr) of the electron should be an integral multiple of h/2ฯ.
•Thus angular momentum of an electron is quantized.
I Wonder, By Jeannie Kirby [ poem ]
I Wonder I wonder why the grass is green, and why the wind is never seen ? Who taught the birds to build a nest, And told to trees to take a rest ? O, When the moon is not quite round, Where can the missing bit be found ? Who lights the stars, when they blow out, And makes the lightning flash about ? Who paints the rainbow in the sky, And hangs the fluffy clouds so high? Why is it now, do you suppose, That Dad won't tell me , if he knows? by Jeannie Kirby
