Image Formation for Concave Mirrors - Case B
To see an object in any kind of mirror, a person must sight along a line at the image of the object. Every person capable of seeing the image must sight along a line of sight directed towards the precise image location. As a person sights within a mirror at the image of an object, there will be a reflected ray of light coming from the mirror to in which person's eye. The origin of this light ray is the object. A multitude of light rays from the object are incident on the mirror within a variety of directions; yet as you sight at the image, only a little portion of the several rays will reflect off the mirror and travel to your eye. To see an object within a mirror and you must sight at the image; and while you do reflected rays of light will travel from the mirror to your eye along your line of sight.
