We show that in the grounded conducting sphere image problem, all the necessary information about the image charge can be found from a mirror equation and a magnification formula. Then, we propose a method to solve the image problem for an extended charge distribution near a grounded conducting sphere. (Contains 4 figures.)

Peer reviewedZwicker, Earl, Ed. – Physics Teacher, 1983
Presents examples of physics activities using common objects such as a tuning fork, umbrella (for double diffraction patterns), and a toy car. Provides questions designed to stimulate student curiosity/interest and which provide models for developing additional units on everyday objects and toys. (JM)
