WebSep 12, 2024 · The point at which the reflected ray crosses the optical axis is the focal point. Note that all incident rays that are parallel to the optical axis are reflected through the focal point—we only show one ray for simplicity. We want to find how the focal length F P (denoted by f) relates to the radius of curvature of the mirror, R, whose length is WebThe best means of summarizing this relationship is to divide the possible object locations into five general areas or points: Case 1: the object is located beyond the 2F point C ase 2: the object is located at the 2F point Case 3: the object is located between the 2F point and the focal point (F) Case 4: the object is located at the focal point (F)
