Moreover, the nodes interleave one another, that is, the nodes of ψn(x) lie between the nodes of ψn+1(x).This can be seen in some examples such as the harmonic oscillator. WebBohr calculated the value of \(\Re\) from fundamental constants such as the charge and mass of the electron and Planck's constant and obtained a value of 1.0974 × 10 7 m −1, the same number Rydberg had obtained by analyzing the emission spectra.
