Abstract
The Poisson spot is a fascinating lecture demonstration. Its simple
explanation can lead to further questions, not only the one posed in the title,
but also questions such as why the simple model that considers only light
passing just outside the spherical object is successful. The Huygens-Fresnel
diffraction model is applied to answer these questions.
