A dentist holds a small mirror 1.9 cm from a surface of a patient's tooth. The image formed is upright and 5.0 times as large as the object.
(a) Is the image real or virtual?
(b) What is the focal length of the mirror? Is it concave or convex?
(c) If the mirror is moved closer to the tooth, does the image get larger or smaller?
(d) For what range of object distances does the mirror produce an upright image?
