Answer
a. Convex
b. Upright
c. The eye is a convex mirror
Work Step by Step
a. The eye’s surface is reflecting the incoming light and is acting like a convex mirror.
b. The photo is right side up. Convex mirrors create upright images. The eyelashes are longer on top too, which is another clue.
c. As we know, the eye bulges outward and is convex-shaped. Convex mirrors make virtual, reduced images.
The ray diagram is shown in 23–19b, where the role of the “mirror” is played by the reflective eyeball in this photo, and the “eye” in that figure is the camera taking the photo (Figure 23-65).
