Numerical solution of 2D Schrödinger equation to simulate the double-slit experiment

Numerical solution of 2D Schrödinger equation to demonstrate emergence of an interference pattern forming after the wave packet passes through two slits. We also check what happens at later stages, you can see the appearance of resonance waves due to the finite size of the box.

The darker colour is the higher the probability density. Hue represents the phase of a wave. Notice that waves with shorter wave-length propagate faster.
