- In any situation, the size, orientation,
- and position of the image can be determined
- graphically in addition to the mathematical
- answers given by the equations. An object in
- front of either a mirror or a lens reflects
- light rays (the reflection of rays from an
- object allows the object to be seen). These
- rays scatter in all directions but are refocused
- by the mirror or lens. For example, if the
- object is a man (represented by an arrow),
- his head scatters light rays, which are then
- refocused and form the image of the person's
- head (the head of the arrow). The question
- remains as to the position of the image.
- In the illustrated situation, the person stands
- behind the focal point of a converging lens. To
- find the image, it is necessary to track the path
