At what distance from himself the boy will see his reflection in the mirror, provided that he is at a distance of 1 meter from him.

The boy will see his reflection in the mirror at a distance of two meters. This is because the distance the light beam travels is twice the distance the boy is from the mirror. That is, the beam of light will travel a distance of two meters. The image in the mirror depends on the total distance traveled by the light from the object to the mirror and back to the object of observation. If, for example, a video camera is placed at a distance of 0.1 meters, then a boy can be viewed through it from a distance of 1.1 meters.
