A cat is located 4.7 m in front of a concave mirror. The mirror has a radius of 1.6 m. Construct a ray diagram to scale following the steps outlined in the procedure here.
(a) Where is the image of the cat?
(b) Is this image real or virtual?
(c) If the image of the cat is 4.5 cm tall, how tall is the cat?
