Derive bohr's postulate of angular momentum from de broglie equation
Answers
The Bohr's postulates -
1) An electron can revolve around the nucleus in certain fixed orbits of definite energy without emission of any radiant energy. Such orbits are called stationary orbits.
2) An electron can make a transition from a stationary state of higher energy
E
2
to a state of lower energy
E
1
and in doing so, it emits a single photon of frequency,
ν
=
E
2
−
E
1
h
where
h
is the Planck's constant.
Conversely, on absorbing an energy,
E
2
−
E
1
when the electron is at energy
E
1
, the electron can make a transition from
E
1
to
E
2
.
3) Only those orbits are allowed for which the angular momentum of the electron is an integral multiple of
h

π
,
Thus,
L
