Energy of a wavefunction
WebMay 4, 2024 · Anyway, quantum mechanics (that is, Schroedinger's Equation) shows that a particle can exist in a region where his energy is lower than the potential energy governing the region (although the wave-function is exponentially decaying), and it even can penetrate a finite potential step, which is known as the Tunnel Effect. Not precisely .. for a ... WebMay 27, 2015 · The physical interpretation behind the increase of energy with the number of nodes can be understood in a very crude manner as follows: Nodes are points of zero probability densities. Since the wavefunction is continuous, the probability density is also a continuous function.

Thus, we cannot in general say that if a wave function has more nodes than another one it will automatically correspond to a state with higher energy. Special case: Schroedinger equation in one dimension
Web7.53. At turning points x = ± A, the speed of the oscillator is zero; therefore, at these points, the energy of oscillation is solely in the form of potential energy E = k A 2 / 2. The plot of the potential energy U ( x) of the oscillator versus its position x is a parabola ( Figure 7.13 ).
