Bohr 2nd postulate
WebMay 3, 2024 · Show that Bohr’s second postulate, ‘the electron revolves around the nucleus only in certain fixed orbits without radiating energy' can be explained on the basis of de-Broglie hypothesis of wave nature of electron. cbse; class-12; Share It … WebBohr’s 2nd postulate tells us that electrons orbit the nucleus only in those orbits for which the angular momentum is an integral multiple of nh/2 (pi). However the question arises is why? why should an electron only orbit a nucleus depending on the angular momentum of the orbit. The answer to that question was answerd by de broglie.

A beam of silver atoms is subjected to a measurement of µx, after which the atoms with µx = +µ0 are passed to a second magnet which measures µz. postulates 3 and 4 that the operator µx has two possible eigenvalues, ±µ0.The same is true for WebInserting the value of λ from equation (2) in equation (1) we get, 2πrk = kh/mvk. mvkrk = kh/2π. Hence, de Broglie hypothesis successfully proves Bohr’s second postulate stating the quantization of angular momentum of the orbiting electron. We can also conclude that the quantized electron orbits and energy states are due to the wave nature ...
