Introduction The phenomenon of Poisson’s spot, a bright spot in the shadow of a circular disk, plays an important historical role in debates about the wave versus particle nature of ... At the beginning of the 19th century, the idea that light does not simply propagate along straight lines gained traction. Thomas Young published his double-slit experiment in 1807. The original Arago spot experiment was carried out a decade later and was the deciding experiment on the question of whether light is a particle or a wave. It is thus an example of an experimentum crucis. At that time, many favored Isaac Newton's corpuscular theory of light, among them the theoretici… WebThe Frenchmen Francois Arago and Jean-Baptiste Biot didn't see eye-to-eye.
