PHY2061 R. D. Field Department of Physics chp40_2.doc University of Florida Mirror Equation Object and Image Position: For spherical mirrors, 11 1 pi f += , where p is the distance from the vertex to the object , i is the distance from the vertex to the image , and f is the focal length . Focal Length: For spherical mirrors the focal length, f , is one-half of the radius of curvature, R , as follows: f = R/2 . Magnification: The magnification is m i p =− , ( magnification equation ) where the magnitude of the magnification is the ratio of the height of the image, h i , to the height of the object, h p , as follows:
