How many times does a mirror reflects a mirror?
If we take 2 mirrors and place them face 2 face, how many times will each reflects what "sees" in the other one? It will go like this: MIrror 1 and mirror 2: 1->2 1<--2 1--->2 1<----2 etc and 1<-2 1-->2 1<---2 1---->2.
The mirrors are reflecting light photons (traveling at the speed of light!) and the light will reflect back and forth until all of the photons have been absorbed by the mirrors. No mirror is perfect and a small amount of energy is lost with each reflection (photons are absorbed by interaction with electrons orbiting atoms and molecules). Also no mirror is perfectly flat and the signal (stream of photons) can degrade as photons reflect off of imperfections in the surface of the mirror. A strong light source will reflect more apparent times than light from an object that is merely illuminated by another light source. You can hold a hand mirror near your eye directed at a bathroom mirror on the wall and experiment with flashlights, etc.
