WebMay 2, 2014 · Imagine an ellipse made of reflective material. Light rays emanating from one focus and reflecting off the ellipse will all be reflected toward the other focus. (This, applied to sound waves rather than light rays, is the principle behind whispering galleries.) Now imagine instead a parabola made of reflective material. WebAn ellipse has two focuses, and the light coming from one source focuses on another one. Take one of the focuses to infinity - and you've got a parabola. As a zero-order …
