The next meetup describes and discusses the quintessential demonstration of quantum mechanical effects and wave-particle duality - the Young's Double Slit Experiment. In this experiment, coherent light is passed through a double slit, and the light that passes through illuminates a screen behind the plate, producing a pattern of fringes, due to the effects of interference between the waves of light passing through both slits. Even a single particle of light, when passed through the slits, can be shown to interfere with itself, and this can be shown for particles of matter (electron diffraction).
This experiment demonstrates two notable features of quantum mechanics - that particles can act as waves and vise-versa (wave-particle duality), and the collapse of the wavefunction - that a particle is described by a wavefunction with an often infinite number of possible states that appears to collapse to a single state when an act of measurement is performed on the particle. This has a profound impact on physics and philosophy, and this will be discussed in detail.
We will be watching clips of the experiment, the outcomes and hold a discussion afterwards. I may be able to get the materials to perform a young's slit experiment (for white light) during the meeting, and if I can then I will attempt the experiment for you to watch.
