Captured light emissions

One thing is for sure, a light beam is alot more difficult to measure than a bucket of water.

Where does all the light go when you turn off your flashlight if you're in a enclosed space that light can't escape?:ironic:

Absorbed and re-emitted in a random direction. If it doesn't hit your retina, then you don't see the light. The random direction cuts the amount of light entering your eye right down, and the fact that you need 3 "blobs" of reflected light on 1 cell to 'see' the light, means that the light bouncing around won't be visible. When there's a constant stream of photons hitting the target, it's a different story- there is enough light to make it "normal" to see the light reflected.

Sorry.....

Thanks Jarl, I was hoping someone would explain. :candle: That was very interesting.

Thanks, I started wondering about that right after I tried to imagine what the ending beam of light from a star that stopped shinning would look like.

Absorbed- even white walls are poor reflectors. Them little photon guys come to a screeching halt, converting their energy to heat. Mostly too little to measure.
