This applet shows how the clusters of rays bouncing off the top and bottom of an object and reflecting from points near F and H in a spherical mirror create an image.
[list]
[*]The arrow labeled D is the object whose reflection we see in the mirror. Move D to move the object relative to the mirror. Move D to the other side of the mirror to switch between converging and diverging types of mirror.
[*]Zoom out and move point B to change the size of the mirror.
[*]Dashed lines show where diverging reflected light appears to have come from.
