Paraboloidal Mirror
73 words 1 min Modified
- The surface of this mirror is a paraboloid
- Focuses rays that are parallel to its axis at a single point, called the focus
- The distance from the vertex to the focus is the focal length
- Can be used as a collimator
- A point source/beam with divergent rays is placed near the focus of a paraboloidal mirror, which causes the rays to become parallel and form a straight line by the Law of Reflection
