WebBohr’s second postulate: The radius of the orbit of an electron can only take certain fixed values such that the angular momentum of the electron in these orbits is an integral multiple of `h/(2π)`, h being Planck’s constant. Mathematical form: m e r n v n = `"nh"/(2pi)` Webλ = h/mv k. Let this be equation (2). Where mvk is the momentum of an electron revolving in the k th orbit. Inserting the value of λ from equation (2) in equation (1) we get, 2πrk = kh/mv k. mvkrk = kh/2π. Hence, de Broglie …
