A meter stick (object) is placed in an upright position in front of a plane mirror as shown in the diagram at the right. The image of the meter stick is equidistant from the mirror. Suppose that the meter stick is equipped with a working eyeball capable of viewing the top and the bottom of its image. The eyeball is located at the 90-cm mark on the meter stick. Using either a ray diagram or geometry, determine …

a. … the location of the intersection of the eye's line of sight with the mirror as the eyeball sights at the top of the image.

b. … the location of the intersection of the eye's line of sight with the mirror as the eyeball sights at the bottom of the image.
