Likewise, the light rays from person B reaches the mirror and gets reflected to reach person A. This phenomenon is known as reflection of light.

If he moves couple of steps away from the mirror, what will happen to the image? The size of the image will be as same as the size of the object. Why is it so?

Three things are required for formation light shadow and reflection shadow, viz.

The size of shadow depends on the distance of source of light and on the angle at which the light rays fall on the object. If the source of light shadow and reflection is closer to the object, a larger shadow is formed than when the source of light is far from the object. If the angle of incident light is smaller, the shadow is longer.

On the other hand, if the angle of incident light is bigger, the shadow is smaller. This explains, why our shadows are longer in the morning and evening and smaller in the noon. Structure of a pinhole camera:
