English: Distribution of the double-slit experiment with observed photons, both slits are open

red graph: ${\displaystyle \frac{N(\alpha )}{N_0}=\underset{leftslit}{\underbrace{2.3\cdot \frac{1}{1.5\sqrt{2\pi }}{e}^{-0.5{\left(\frac{x+1}{1.5}\right)}^2}}}+\underset{rightslit}{\underbrace{2.3\cdot \frac{1}{1.5\sqrt{2\pi }}{e}^{-0.5{\left(\frac{x-1}{1.5}\right)}^2}}}}$

Code: 2.3*1/(1.5*sqrt(2*pi))*exp(-0.5*((x+1)/1.5)^2)+2.3*1/(1.5*sqrt(2*pi))*exp(-0.5*((x-1)/1.5)^2)

Note: The factor 2.3 is optional. With the factor 2.3 the maximum value is approx. 1.
