1. The problem statement, all variables and given/known data A convex spherical mirror has a radius of curvature R = 20.0 cm and produces an upright image precisely one-quarter the size of an object. Calculate the separation distance between the object and its image? 2. Relevant equations M = (image height)/(object height) = h'/h = -q/p 1/q + 1/p = 1/f q = length from mirror to image p = length from mirroe to object f = focal point 3. The attempt at a solution FOR FINDING p (length from mirror to object) h = 4h' h'/h = -q/p h'/4h' = -q/p q = -p/4 1/(-q) = 1/f - 1/p 4/p + 1/p = 1/f 5/P = 1/10 P = 50 I know this cannot be right because when i go to calculate q it is greater than the focal point and that does not work. Any help would be great.
