Physics Ex-49 The mirror equation is a geometrical derivation for solving problems with curved mirrors. Where: f = focal length do = Object distance di = Image distance and Where: M = magnification factor hi = height of image ho = height of object  Physics Ex-49 Where: f = focal length do = Object distance di = Image distance Be sure to observe the following sign conventions when using the mirror formula: ① All distances are measured from the vertex of a curved mirror. ② Distances of objects and real images are positive. ③ Distances of virtual images are negative. ④ Object and image heights are positive when upright and negative when inverted. Parabolic mirrors are used as reflectors for searchlights, flashlights, projectors and automobile headlights.  Physics Ex-49 Question-1 An object is 60 cm from a concave mirror whose focal length is 15 cm.
