Question

Bohr's postulate that mvr =nh/2pie
is proved mathematically by
1) Pauli's exclusion principle
2) Hiesenberg's uncertainty principle
21 de Broglie wave nature of the electron
4) Sommerfeld theory​

Answer 1

Answer:

de Broglie wave nature of the electron

Explanation:

mvr=nh/2π: angular momentum of the electron

The idea of de Broglie waves or de Broglie matter waves.

A substance particles electron or proton and

they are considered to be "particle" might have

"wave nature".

Answer 2

Bohr's theory of angular momentum of an electron is mathematically proved by de Broglie's wave nature of electrons.

(option 3)

• Bohr gave his postulate on hydrogen atom that the angular momentum of an electron in a given stationary state is expressed as- $mvr=n.\frac{h}{2\pi}$
• de Broglie later proposed the dual nature of matter and stated that electrons have momentum as well as wavelength.
• He gave the relationship-  $\lambda=n.\frac{h}{mv}$
• This proved the Dual behavior of matter.
