Hello, I have a question or perhaps a few questions regarding light and mirrors. When we point light at a mirror, it gets reflected back. But we can see the point light (assuming that it is a laser for the sake of simplicity) at a surface opposite to the reflective surface of the mirror. What piques my interest and leaves me perplexed is that the light is cast on the mirror, but it is also cast on another surface but the same is not true for things other than light ! In fact, I have conducted a few simple experiments to see the interaction of light with materials and how light sources act. For example, a fire does not act the same as a torch or a laser and it casts a shadow and a laser light is not reproduced or mirrored on another surface when we point at a reflective surface which is not mirror, for example, glass, even one with covered back or a metal like steel. We can argue that it depends on the light emitting radius to the body ratio but I think that becomes irrelevant at an angle. I would like to know what exactly is going on and how can light be duplicated or reproduced. Even if it loses it's intensity to abide by the law of conservation of energy, how exactly does this happen ? And why is it that other light emitting sources do not exhibit similar characteristics ? Kindly provide me with a clear and an elaborate explanation. Thank You.
