One slit

This experiment allows you to watch the diffraction through a slit when it is not so narrow to consider it a punctual source.

To try to simulate this experiment with the same previous tools we assume that the slit is formed by a lot of punctual sources (N).

We get the interference pattern on a screen parallel to the line of the punctual sources and far from them.

Scheme of the simulation

A:	width of the slit, in nanometers.
l:	wavelength of the light, in nanometers.
Y:	central interval of the screen that we observe, in centimeters.
L:	distance between the slits and the screen, in meters. (L >= 1)

We can change these parameters with the window of settings of the experiment when we do a simulation.
