Mirrors are everywhere. You can walk past any number of them during the day. Some are windows, some are just relective surfaces, but a human's natural impulse is to look at their reflection whenever they walk by anything in which they can see themselves. Have you ever stopped to wonder how that works? Well, I am now going to explain it as clearly as I can.
Did you know that your skin color is not the color you think it is? You might think it's black or white or brown or whatever, but really, it's every color except the one you think it is! See, objects absorb color. I said that in an earlier post. (They also subtract color, but I'm not getting into that now because it would get too complicated.) Well, your skin absorbs every color except the one you think it is. In fact, it rejects the color, so that's what you see. When you look in a mirror, the rays of light bounce off because the surface doesn't absorb it.
Also, things that don't reflect can also be mirrors. Signs that show up when the carlights hit them are reflecting the light from your lights. Cats eyes reflect things as well. When the eyes of a cat or nocturnal animal are caught in the headlights of a car, the eyes glow back at us due to a reflective material in the backs of their eyes. Let's just hope that you brake before you hit the animal, eh?
That's all. Adios!
