Interactive particle-in-a-box wavefunctions in Jupyter

A very quick plot of particle-in-a-box wavefunctions with interactive control over the box length, $L$ – this kind of thing is very easy with Jupyter and ipywidgets' interact method: Just define a function to plot the wavefunction for a provided argument $L$ and pass it to interact along with a range and stepsize of values of $L$ and a slider will appear above the plot. Event callbacks and range-checking are all handled for you.

The Jupyter Notebook can be downloaded here or using the nbviewer website. Some example (static!) images of the output plot are given below.
