Shining Light Through Solid Balls Using Quantum Mechanics—Poisson’s Spot Experiment

In this video I show you how it is possible to shine light through a sphere using the wave-like nature of light. This spot in the center of the shadow of a sphere is called Poisson’s spot or Arago’s spot. It is a result of the diffraction of light around the edges of the sphere that constructively interfere right at the center. Then I show you what it actually looks like to look at the center of poisson’s spot. Does it look like the light is actually going through the ball?
