30.   A dentist’s mirror is placed 2.0 cm from a tooth. The enlarged image is located

5.6 cm behind the mirror. (a) What kind of mirror (plane, concave, or convex) is being used? (b) Determine the focal length of the mirror. (c) What is the magnification? (d) How is the image oriented relative to the object?

 

Planar and Convex mirrors do not create larger images, so this must be a Concave Mirror!

 

 

 

 

Since the magnification is positive the image is upright.

 

Concave Mirror!

The image is upright.
