3.5 Parabolas, Ellipses, and Hyperbolas - MIT …
ocw.mit.educollector and a TV dish are parabolic. They concentrate sun rays and TV signals onto a point-a heat cell or a receiver collects them at the focus. The 1982 UMAP Journal explains how radar and sonar use the same idea. Car headlights turn the idea around, and send the light outward. Here is a classical fact about parabolas.
