~~when you switch it off it no longer recieves the electrical current, so it goes to sleep, which is what i am going to do after answering your question... nite~~

I have always conceived of light dissipating over a distance as merely
a factor of set amount of light having to fill an ever expanding volume.
Then it struck me the other day that it must really dissipate.
What if you built a completely enclosed room covered with mirrors.
Inside you had a light bulb. You turned it on then turned it off.
Would the room remain filled with light? If not (which I assume is the
answer) where did the light go?
If the answer is that mirrors are not 100% reflective, what if you could
build a room with 100% reflective walls? Would the light just keep
bouncing around? And if you could do that, and you left the light on would
the room keep getting brighter and brighter?

this question makes no sense... i really dont even know why i;m answering it... i feel like i'm being "punked"... but the light has no space or weight to it... so it cant like evaporate or go anywhere... you sever the circut needed to power the light when you turn it off... the filament inside the bulb isnt producing light when the switch is off because there is no electricity running through it.....
simple as that

Light is constantly being reflected and absorbed by the objects in the room. If the room is closed and opaque, all the light is absorbed by the objects in the room, including the walls and ceiling. If the room has windows, some of the light escapes outside.

It is consumed in the process of energizing the atoms in the objects that surround the light source. That energy is transfered to heat etc.

light bulbs work by electricity flowing through the fillament in the bulb, once the electricity is removed from the fillament the bulb darkens. so in effect no natural light is created or lost

It transforms itself into dark light.

no power ,no light it goes nowhere as it was going anywhere to begin with...it simple is,until it is not...read a science book about edison thomas alva Edison....might help
