Safeopedia Explains Parabolic Mirrors
Parabolic mirrors have the ability to concentrate all the energy reflected at them into one focal point or to reflect parallel beams from an energy source placed at their focal point. An example of a parabolic reflector is in a satellite dish, which is a commonly used application of this technology. Car headlights also have a light source placed at their focal point.
