A dentist uses a spherical mirror that produces an upright image of a tooth that is magnified four times. (a) The mirror is (1) converging, (2) diverging, (3) flat. Explain. (b) What is the mirror’s focal length in terms of the object distance?
Added by Alicia C.
Step 1
Since the image is upright and magnified, we can infer certain properties about the mirror. Generally, a real image formed by a mirror is inverted, while a virtual image is upright. Since the image of the tooth is upright, it suggests that the image is virtual. Show more…

A dentist uses a spherical mirror to produce an upright image of a patient's tooth which is magnified by a factor of 4 when placed 2 cm from the tooth. (a) What type of mirror - concave or convex - is being used? (b) What is the focal length of the mirror?

A dentist's mirror produces an upright image of a tooth, magnified three times. (a) Is the mirror concave or convex? (b) If the dentist holds the mirror $2.0 \mathrm{~cm}$ from the tooth to achieve this magnification, what's the mirror's focal length?
A dentist uses a curved mirror to view teeth on the upper side of the mouth. Suppose she wants an upright image with a magnification of 2.00 when the mirror is $1.25 \mathrm{~cm}$ from a tooth. (Treat this problem as though the object and image lie along a straight line.) (a) What kind of mirror (concave or convex) is needed? Use a ray diagram to decide, without performing any calculations. (b) What must be the focal length and radius of curvature of this mirror? (c) Draw a principal-ray diagram to check your answer in part (b).
