A concave mirror forms a real image twice as large as the object. The object is then moved such that the new real image produced is three times the size of the object. If the image was moved 73.9 cm from its initial position, ... a) ... how far was the object moved? (If it was moved closer to the mirror, the result will be negative. If it was moved farther away from the mirror, the result will be positive). Submit Answer Tries 0/100 b) ... what is the focal length of the mirror? Submit Answer Tries 0/100 Post Discussion Send FeedbackAn object is located at a distance of 101 cm from a concave mirror of focal length 22.5 cm. Another concave mirror of focal length 5.81 cm is located 22.5 cm in front of the first concave mirror. The reflecting sides of the two mirrors face each other. Assume the second mirror is partially silvered so that the light rays from the object go through it, reflect from the first mirror, and then reflect from the second mirror. a) What is the location of the final image formed by the two mirrors?
