A convex mirror with a radius of curvature of 0.550 m is placed above the aisles in a store. Determine the image distance of a customer lying on the floor 3.1 m below the mirror.
1/f = 1/do + 1/di. Your focal point is half the radius, so .275 m focal length and that would be a negative point because it is convex. So 1/f - 1/do = 1/di. 1/-.275 m - 1/3.1 m = -3.959 whose inverse is -.253 m.
So the image distance is about -.253 m
