Geometric optics and the “hairy ball theorem”
Applications of the hairy ball theorem to the geometrical optics are discussed. When the ideal mirror, topologically equivalent to a sphere, is illuminated at every point, the “hairy ball theorem” prescribes the existence of at least one point at which the incident light will be normally reflected....
