Just curious, and sound stupid.<br />If we direct a light source, say a torch, to a mirror, the light will be reflected. My question: Does the mirror return the light 100% or some of the light pass through it? Or say if the mirror really 100% return the light, is it possible to trap the light in a room made of mirror (maybe sphere shape) then we turn the light on and then the light will bounce around infinitely, even after we turn off the light source and the room is still bright cos the light is still there bouncing around, is it true? <div class="Discussion_UserSignature"> </div>
