Even the best mirrors absorb or transmit some of the light incident on them. The highest-quality mirrors might reflect 99.997% of incident light intensity. Suppose a cubical "room," 2.14 m on an edge, were constructed with such mirrors for the walls, floor, and ceiling. How slowly would such a room get dark? Estimate the time required for the light level in such a room to fall to 1.00% of its initial value after the only light source in the room is switched off. (Assume that the average distance light travels between reflections is half of the maximum possible distance.)
