Poisson’s Spot is proof that even if you’re right about things, you can be humiliated forever. Find out why this physics concept has caused the name Siméon Poisson to live in infamy for almost 200 ...

The original 'Poisson spot' experiment had a crucial role in proving the wave nature of light: because of the way that waves diffract, light shining at a circular object casts a bright spot in the ...

This experiment demonstrates Poisson’s Spot, a curious optical phenomenon where light bends around a circular object, creating a bright point in its shadow and revealing wave behavior of light.
