The wave functions for a quantum harmonic oscillator are quite similar to the case of the infinite square well. One important difference is... (choose the correct option). The wave functions for the harmonic oscillator decrease in wavelength as energy increases; for the infinite square well the wavelength increases with energy. The lowest possible wave function for the infinite square well has zero energy; for the harmonic oscillator the lowest is not zero energy. The wave functions for the harmonic oscillator come from solutions to the Schrodinger equation; for the infinite square well the Schrodinger equation is not used. The wave functions for the infinite square well go to zero at the turning points; for the harmonic oscillator they do not
