1. The problem statement, all variables and given/known data An object is placed in front of a convex mirror with a 45.6-cm radius of curvature. A virtual image half the size of the object is formed. At what distance is the object from the mirror? 2. Relevant equations 1/f=1/d0+1/di hi/h0=-di/d0 3. The attempt at a solution hi=-1/2h0 f=45.6/2=22.8 di=-1/2d0 1/22.8=1/d0-2/d0 d0=-22.8 This is my solution but this is nor correct.....anyone plz tell me the mistake. thanks!
