Fresnel diffraction experiment 1/7: official trailer
Is there light in the center of a shadow from a black disk? What is the shadow of a hole milled in an opaque screen? Can adding light to light create darkness?
The Institut Fresnel releases a series of short videos answering various questions about light and optics, providing an illustration of physical optics concepts such as diffraction, interferences, imaging and microscopy.
See our official trailer below (sounds very pro like that). More videos on the Institut Fresnel youtube channel.
