1. A dentist examines the cavity in a person's tooth using a concave mirror of focal length +2.0 cm. If the cavity is 1.5cm from the mirror's surface, (a) where is the image located, (b) is it real or virtual, and @what is its size? 2. The observation mirror in a store is a convex mirror and has a focal length of -2m. Calculate (a) the image location and (b) the image height of a 1.5 m-tall boy standing 4.0 m from the mirror. 3. A 1.6 m-tall man stands in front of a plane mirror. How tall is the image form? Useful formulae: where: = 1/d, + 1/d, f- focal length do- distance of object from mirror di - distance of image from h'- size/height of image h- size/height of object h' = -hd,/d.
