Will light stay in a box lined with mirrors forever or until it is opened?

Notwithstanding quantum mechanical effects from quantum field theory involved in photons escaping confined regions that I'm not qualified to answer in regards to, and supposing that you had *ideal* mirrors that reflected all of the incident energy of the photon and if you could seal the box (or probably a better aparatus would be a sphere) before your incident light beam escaped, then I believe the answer is yes.\n\nI'm fairly sure that this is not quite as theoretical as I've made it sound by invoking ideal mirrors and actually is practical.  I'm fairly sure that there is a research group here at my University working on storing information encoded in photons by basically trapping it between two mirrors to bounce back and forth until released for further processing.  I haven't been able to find a link to any research publications on that, but I'll update you if I locate one.\n\nI hope that helps.

Magnifying mirrors are concaved inward and work by focusing the light on a point such that the image is larger than the original object.\n\nhttp://physics.bu.edu/py106/notes/Spherical.html

In order for your eyes to register something, light must first be shined on, and reflected off of a particle.  If the light has nothing to reflect off of, your eyes will not see it.  Space consists of nothing, making it appear completely black to your eyes.

wow, what a cool way of thinking!  I have wondered sometimes that when I walk up to a mirror and then walk away, where does my mirrior image go?  Does it go do something else until I summon it to the mirror again?

You see a mirror in a mirror in a mirror in a mirror ......\nThere are various gadgets using this effect. \nFor instance if you put a lightbulb between the two mirrors and look throug the one way mirror you will see (depending how parallel you've managed to put the mirrors) lots of lightbulbs disappearing into infinity. I know 'cause I've done it!

light travels as fast as it always travels, no matter what it shines through. Things block light, but it doesn't slow it down.

sure its called a mirror

I cannot tell you whether or not it has been done...\nBut I will never be truly "trapped" even with a mirror with a fairly high finish (aka 1-2 microns) there is still a loss every time it "bounces" off the mirror + if you do not do it in a vacuum there will be atomspheric losses as well.\nHenceforth if it is "trapped" it wouldn't stay there for long..

No surface can be 100% reflective. If you shot, say a laser at the most reflective surface possible, the reflected light would be less than the original beam.\nThere is no material that can allow light in and no light out. If you did create the sphere, you would need a little hole to aim a light source at, then you would have to close it quickly with the light source still shinning at the hole. Theoretically, with a 100% reflective surface and a vacuum inside the sphere, it would bounce around forever, until you broke it. A small flash would be seen, but the light energy would not compound and blow up.

use black light,u will find it in any good store

It is stored in the electromagnetic radiation produced by the event.  The "container" of this radiation is expanding outward on the surface of a sphere that is increasing in radius at a rate of 300,000 km/s, the speed of light.  Thus, we can indeed look back in time if we wait for this sphere to pass our location.  This is what we are doing every time we look up at the night sky.  We are seeing the electromagnetic radiation caused by events that happened long ago.  Even the light that we see coming from Alpha Centauri, our closest stellar neighbor, left there 4 years ago.  So when we look at Alfie-Cent (its "street" name) we are looking at an event that was "stored" for 4 years.

Yes it can. If you have two mirrors exactly facing each other, an infinite amount of reflections are made back and forth. You should try it.

playing around with mirrors....and light.....and lenses

You neglect to mention whether the light hits the mirror on its axis of rotation.. assuming that it does, the reflected ray is delfected through twice the nagle that the mirror moves.. thus, 40 degrees.\nLook up "optical lever"

It depends on the length of the mirrors.

Real mirrors aren't 100% effective, so each time the light bounced off a mirror, some would be absorbed.  Plus, there's also you with your flashlight in the room, and most of the light that hits you would be absorbed.  So, the answer is that the light would be absorbed and converted to heat, just like it would in a room without mirrors.

If it reflects all the light, it appears white. If it absorbs all the light, it appears black.
