Question

(a) A10-cm-tall mirror bears the following advertisement: “Full-view mini mirror. See your full body in 10 cm.” How can this be?
(b) A popular novelty item consists of a concave mirror with a ball suspended at or slightly inside the center of curvature (Fig. 23.26). When the ball swings toward the mirror, its image grows larger and suddenly fills the whole mirror. The image appears to be jumping out of the mirror. Explain what is happening.
