WebSep 12, 2024 · The distance along the optical axis from the mirror to the focal point is the focal length f of the mirror. A convex spherical mirror also has a focal point, as shown in Figure \(\PageIndex{3}\). Incident rays parallel to the optical axis are reflected from the mirror and seem to originate from point \(F\) at focal length \(f\) behind the mirror.
