Question

Angular momentum of the electron is quantized integral wavelengths

Answer 1

Answer:

___________________________

According to Bohr, the electrons are moving in circular orbits around the atom(Hydrogen). This circular orbits called stationary states. They will have angular momentum equal to integral multiple of h/2*pi. If you do some simple calculations you can see that the perimeter of this circular orbits will be integral multiple of de Broglie wave length of electrons.
