An electron reaches a screen by passing through one of two slits.
Important: There is no way to tell which slit it passes through without changing the experiment.
An electron reaches a screen by passing through one of two slits.

What this is an example of
The amplitude A1(x) for finding the electron at position x after it has passed through slit number 1 is just the value of the deBroglie wave which has passed through slit number 1.
Examples
--- What this is an example of
The amplitude A2(x) for finding the electron at position x after it has passed through slit number 2 is just the value of the deBroglie wave which has passed through slit number 2.
Examples
--- What this is an example of
The amplitude for finding the electron at position x is just the sum of the deBroglie wave amplitudes for slits 1 and 2.
A(x) = A1(x) + A2(x)
The probability of finding the electron is larger in some places and smaller in others.
