D2 – Young’s experiment of double slit

G1 –  Young’s experiment of double slit

 

Our most recent experiment is Young’s double slit experiment. We made a laser go through the double slit and we studied both the destructive and the constructive interferences created by it on the wall. Originally, the beam was circular of shape, but, after having passed through the slits, there were several points of interference, and on the wall the spots where the interference had a destructive effect followed a regular pattern alongside with the spots where the effect of the interference was constructive. The brightest spot was the one in the middle. The less broad the slit was, more there was an inteference.
