| I am burning a candle infront of a mirror in a room. Will the mirror image acts as a separate light source? What will be the difference between buring a candle in front of a mirror in a closed room and burning two candles(without mirror in the room)? In short the question can be reframed as " Do the mirror images of light source act as a separate light source?" regards, Yogesh |

| > I'll assume for the moment it's a serious question. There's only one souce of light in the room. All the mirror does is reflect back that portion of the light that would otherwise have been absorbed by a wall or some such thing. |

Expect about 30% brighter room with a nearby mirror (any better approximations?). 1 Less than half the light from the candle reaches the mirror (from 1 side). 2 The mirror is only about 90% efficient. 3 A white wall is nearly as effective, so the mirror will give a lot more light than a black wall. There is a fixed amount of light output from the candle though, be an intereresting geometry problem to see if many mirrors approaches this value, the location for the measurement of brightness has to be considered.
