The working principle of parabolic mirrors is based on the mathematical concept of a parabola. A parabola is a two-dimensional, mirror-symmetric, open U-shaped curve, and a paraboloid is the three-dimensional extension of this concept, often referred to as a paraboloid. An important characteristic of a paraboloid is that parallel rays of light will converge at the focal point regardless of where they strike the mirror.
