To find the image length, of a 4-foot-tall object in a spherical mirror with a focal length of 2 feet, L=4(2/o-2)^2 can be used, where 2 is the distance, in feet, of the object from the mirror. What is the image length of the object when it is 1.5 feet away from the mirror?

L = 4 (2/1.5 -2)^2

=4 (2/3 -2)^2

= 4 (-2/3)^2 = 4* 4/9 = 16/9
