Double Slit Experiment

A little animation I made for my computational physics class. A gaussian wavepacket passes through a symmetric double slit. Note the interference present on the right (the multiple lobes). The Wavefunction is interfering with its self.

How was this made? Was it using Schrödinger's equation? and finite difference method? and what does the white represent, probability?

@MikeM8891 This was made using what known as an alternating difference implicit method, a type of finite difference method. You can read more about it in an American Journal of Physics article: Galbraith, I. et al. American Journal of Physics, 52, 60, 1984.

@MikeM8891 The white is in fact probability. IDL is nice because it has complex valued types!

I have the answer to the double slit experiment, the meaning of life, and the cause of the singularity that gave rise to all that is.

But I'll never tell.

Nice video!

In my video Quantum Mechanics an artist view Time has symmetry and geometry that can explain the two slit experiment of Quantum Physics.

construction of the entire experiment and measuring apparatus's, is key I believe. If we can construct a machine that is greater than 99.8% in symmetrical design, the test will be different, not impossible and more successful. (Hopefully)

Well, now someone with some $ can make me proud!

Correct, but if you try to measure this phenomenon, the "photon" (using this term very loosely), will only go through only one slit and not both and there will be no interference pattern. Or will it? There has not been an effective experiment preformed since the mid 80's, where it was proved that placing the measuring device in different locations would result in slightly different patterns. So finding a way to measure that involves almost perfect symmetry of the
