A parabolic reflector is a curved surface that is shaped like a parabola. It is designed to collect and focus waves, such as light or sound, onto a single point known as the focus. This property makes parabolic reflectors useful in various applications, including satellite dishes, telescopes, and solar cookers. In a parabolic reflector, incoming waves that are parallel to the axis of the parabola are reflected towards the focus. This principle is utilized in devices like radio telescopes and flashlights, where efficient collection and direction of energy are essential for optimal performance.
