WebFocal length Focus is defined as the point through which the reflected light rays pass (or appear to pass) when incident light rays are parallel to the principal axis. It is located at the midpoint of pole and centre of curvature. The distance between the pole and the focus of the mirror is called the focal length of the mirror. Hence, f = 2 R WebThe outside mirror on the passenger side of a car is convex and has a focal length of -6.0 m.
