Where does the surrounding light go, when you turn the switch off in a closed room with no exit or windows?

All of the light "floating" in the air is composed of photons which are eventually absorbed by the atoms in the room and converted into heat.  This heat eventually dissapates through the walls and radiates outside the room.  Of course, there is an imperceptable delay between when the last photon leaves the light and is absorbed by the walls, but this happens at the speed of light and can't be seen by you or me.

Say away from H20 and LIGHT

It bounces around and out of the room. Since this happens at the speed of light, you don't notice a gradual fading of light so much as a sharp transition to darkness.

This is a perfect question for the section called 'corporations'.\n\nThe answer is 'NO'. Even though you leave the light switch on, the burned out bulb breaks the circuit and uses no electricity.

closed off. like you cant see it.

Well, since, as stated before, darkness is the absence of light, it travels at the exact speed of light in a given medium. For example, if you turn a light on in a darkened room, it gets bright very quickly (exactly how quickly will depend on the type of light bulb or the colour of the light you use), but when you turn it off, it gets dark at the same rate. Though darkness isn't something that really "travels", what you're measuring is how fast light dissipates, which is at the speed of light!

turn off lights... use a flashlight for sun. see how the opposite side is dark but the front is light.

No\n\nYou unplug it dies

Light is cool stuff.It acts like radiation but when it hits something it act like a particle.You cant see light until it hits something and it releases its energy.So most of the light after you turn the switch off hits something and ceases to be but a very small amount might be lucky to shine out to open sky and even less might leave earth.It will keep going till it hits something all happening at the speed of light.Like looking at very distant stars ,its taken billions of years for the light to reach us.The star is long gone switched off but we are still seeing the light from it very diffused but what we see hasn't hit anything on its journey and it's an infinitely small amount of what originally left that star/sun

did you mean how does a light sensor work?

In the house I grew up in, lights used to come on in the middle of the nights all the time.  Just randomly all the lights in the living room would turn on then in the kitchen and all the bathrooms.  It was super freaky.

get one of those electrical outlet timers that are used for turing lights on etc.. and lock it in the closet with your router, and or pc

I can't stand it when people leave a room without turning the lights off. I usually dash back inside the room after the person leaves, to correct the problem. I'm not like that with most things but...

The more natural direction someone may brush a switch accidentally, is down. The OFF position is the better default position for anything electrical. Also, it is easier to read the little word "OFF" from the top side. Because the Americans probably designed the switch first, I would say the Europeans were being different to design it the other way around. Think about it.

Since you already have some real answers, I can't resist.\n\n"Turn off the light when you leave the room!"\n\n -- My dad

Use a night light.  Turn it on everynight before you go to bed.  I'm sure after awhile you'll forget about turning it on and won't even realize it.  Also, lots of times if you open up your curtains or blinds a little bit light from outside comes in.

Two things....\n1) Air vent closed\n2) the main way is closed
