- A quantum simple harmonic oscillator consists of an electron bound by a restoring force proportional to its position relative to a certain equilibrium point. The proportionality constant is 8.11 N/m. What is the longest wavelength of light that can excite the oscillator? ps:- answer is not 443.68Font Paragraph Styles Voice Sensitivity 5. The dispersion relation for propagating waves is the equation w = w(k) giving the angular frequency as a function of the wavenumber. A free-electron will have the energy-momentum relation E = 2m Use this relation, in conjunction with Planck's equation and De Broglie's equation, to determine the quantum mechanical dispersion relation for the wave associated with a free electron.
