Question

100%

While looking at her image in a cosmetic mirror, Dina notes that her face is highly magnified when she is close to the mirror, but as she backs away from the mirror, her image first becomes blurry, then disappears when she is about 38.0 cm from the mirror, and then inverts when she is beyond 38.0 cm. Based on these observations, answer the following questions about the mirror.

(a) What type of mirror does Dina have?

convexconcave

(b) What is the focal length of the mirror?
cm

(c) What is the radius of curvature of the mirror?
cm
