| Apr 9, 2014 at 8:33 | comment | added | Wouter | The actual way we deal with plane waves is by constructing wave packets. Basically, we assume $$e^{i(kx-\frac{\hbar k^2}{2m}t)}$$ are valid solutions (for every $k$) and then go on saying: well, then the general solution is a linear combination of these. $$\Psi \propto \int_{-\infty}^{\infty}{dk\phi(k)e^{i(kx-\frac{\hbar k^2}{2m}t)}}$$ If we choose the $\phi(k)$ right, this function is normalizable. Of course in reality the plane wave is an idealization like the frictionless surface, so unusual behaviour is not entirely unexpected. | |
