Tips and Tricks on Parabola


The parabola has an important reflection property. Any ray or wave that originates at the focus and strikes the parabola is reflected parallel to the axis of symmetry. For this reason, an instrument such as a flashlight or a searchlight uses a parabolic reflection, with the bulb located at the focus. The reflector redirects light that would otherwise be wasted parallel to the axis, so that a straight beam of light is formed.

By the definition for the parabola e = 1 If e > 1 the it is Hyperbola, e = 0 for a circle, e < 1 when it is ellipse
