An object is placed in front of a convex mirror with radius of curvature = 17 cm. The object's height is 3.5 cm and it is initially 25 cm in front of the mirror. Find the (a) location and (b) height of the image. Next the object moves closer to the mirror, so the object distance is 5.1 cm. Again, find the (c) location and (d) height of the image. (e) What is the ratio of the image height when the object distance is 5.1 cm to that when the object distance is 25 cm?
