Solution:
The drawing shows that you
see twice as much of yourself as the length of the mirror.
Suppose that the mirror is hung flat against the wall
so that the top of the mirror is halfway between your
eye and the top of your hat. Lines 1 and 2 show the "line
of sight" from your eye to the mirror and from the
mirror to the top of your hat. Lines 3 and 4 show the
"line of sight" from your eye to the mirror
and from the mirror to your foot. |

The horizontal lines show the heights
of the mirror's top and bottom. The distance from the
top of your hat to the horizontal line indicating the
top of the mirror is the same as the distance from this
line to your eye. The distance from your eye to the horizontal
line indicating the bottom of the mirror is the same as
that from this line to your foot. Thus, you can see twice
the length of the mirror.
Try drawing the figure closer to the mirror or farther
away. Although the angles change,
the part of the body seen in the mirror is always twice
the length of the mirror. |
