FIGURE 4

In Figure 4., an observer sees an image of an object place at P in front of a plane mirror. When the object is moved to X, the image is seen at Y. This has caused the reflected ray towards the observer to change with respect to the plane mirror. By considering the changes in the incident and reflected rays,
