Circular paraboloid. A parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a reflective surface used to collect or project energy such as light, sound, or radio waves. Its shape is part of a circular paraboloid, that is, the surface generated by a parabola revolving around its axis. The parabolic reflector transforms an incoming plane wave traveling along the axis into a spherical wave converging toward the focus.
Proper Positioning. Bicycle reflectors reflect the upper beam of a carâs headlamps. To ensure you are visible on the road at night, position your safety equipment properly. Rear reflectors, for example, should point straight back.Inspect all installations regularly, tightening loose screws that can cause reflectors to move out of place.t night, a reflector makes you visible from 500 feet way, giving a car going at 60 mph about twice the distance it needs to come to a stop. On the other hand, if you forgo reflectors and wear blue or black, you become noticeable at 55 feet of distance, allowing a driver less than one second to react after he sees you.
