Give de-Broglie's explanationof Bohr's second postulate. |
|
Answer» SOLUTION :According to Bohr the ANGULAR momentum of the electron is an integral multiple of `h//2pi` i.e., `mvr=(nh)/(2pi)` de-Broglie argued that these ELECTRONS EXHIBIT wave propertyhaving stationary wave patternhaving nodes at the ends. The total distance travelled by a wave is an integral multiple of the wave length . i.e., `2pir=nlambda` `lambda=h/P=h/(mv)` `therefore 2pir=(nh)/(mv)` `mvr=(nh)/(2pi)` But angular momentum of the ELECTRONIS L=mvr Hence `L=(nh)/(2pi)` |
