In the figure below you can see the rays of light which are reflected from the upper and lower edge of the mirror surface into the eyes of Mr. Huber. As you can see, no matter how big (or small) his distance is to the mirror, Mr. Huber always sees the same portion of his body in the mirror.

To move Mr. Huber move the blue dot in the picture (bottom left).
