Young’s double-slit experiment with waves, in 3D

This 3D remake of the video shows Young’s double-slit experiment with classical waves. An oscillating source is emitting circular waves on one side of a wall with two small holes. Part of the waves is able to go through the holes which, according to the Huygens-Fresnel principle (see –Fresnel_principle ) act almost like point sources. The resulting waves then create interference patterns, with oscillations depending on the wavelength, and the geometry of the slits. To obtain visible patterns on the right side of the wall, the waves had been scaled up vertically. The interference patterns are more visible in the second half of the video, showing the energy of the wave. This simulation has two parts, showing the same evolution with two different color gradients: Wave amplitude: 0:00 Wave energy: 1:05 In the first part, the color hue depends on the height (amplitude) of the wave, with yellow indicating positive values, and purple indicati
