If you flash a light in a mirrored box, will it be light inside forever?

Theoretically, yes, but practically, no.  A mirror absorbs a small percentage of the light it receives, reflecting the rest.  After many levels of reflection, the light will fade out.

You are correct that the box is the color of the light it reflects.   Alternatively, you can say:  The box is the color not absorbed by the molecules on its surface.     But you would never say the box is the color absorbed by the molecules on its surface.   That is, your last statement is false.

It works on photo electricprinciple.\n\nBasic is a light source and a reflective surface(mirror).\n\nCircuit either stay normaly open or shute but when the beam is broken it provides a signal which in turn operates a system, say bell or a motor, that can open a door.

b/c a constant amt. of electricity is going into it, and it will only get brighter if you add more electricity to it, or get a brighter bulb!

B.  A convex mirror will make light diverge, and no mirror will *alwats* give a inverted image, because it depends whether you're closer than the focal point for a concave lens.\n\nThink about those little round mirrors on buses and huge trucks, and how small the image is.  Those mirrors are convex.

It works by having little mirror slices at different angles. As light is reflected off the orb, the little slices separates the light into several colours briefly and the process is repeated.

No, as da 1st prism 'll split it into da spectrum (VIBGYOR) & da 2nd 'll just refract da spectrum & not convert it again into white light.

no, it is infared light, which is lower energy than regular light. plus it is a very weak, un focused siganl that only transmits for an instant.

A mirror CAN make things look upside down.  Stand in front of a mirror and hold a book up so you're reading the cover.  Now, turn the book so the cover faces the mirror and you can see the book cover in the mirror.  Normally you would rotate the book about a vertical axis, THIS is when the left and right reversal takes place.  You could instead turn the book upside down.  Then the reflection of the cover WOULD be upside down, and not backwards.\n\nOther answers given:\nRefraction does not happen. Only reflection.  Refraction has to do with the bending of light when it goes from one medium (such as air) to another medium (such as water).  It has nothing to do with the question.\n\nBecause our eyes are next to each other.  Close one eye and prove to yourself that that answer is nonsense.\n\nAlthough it seems backwards its really not.  Prove this is wrong by holding a book to a mirror and trying to read it.

I heard it said that Thomas Edison said, after failing 10,000 time to successfully invent the light bult, "I have discovered 10,000 ways this will not work."\n\nMy point is this.  You'll come out wiser, or foolish for having missed the opportunity.

You need one that is fully mirrored.\n\nThis is needed - almost - in some types of laser. A cylinder is used where on side is a perfect mirror (as perfect as one can get) and the other side is a partial mirror (say 99% of the light is reflected, the rest goes through like glass).\n\nThis sort of configuration is used to build up the strength of the lasing effect inside the cylinder and make for a better laser.\n\nOther types of modern lasers are efficient enough that this isn't necessary. Enough lasing is done down the length of the laser that no reflections are needed.\n\n(This isn't to be confused with the other concept of a "light trap" which is to keep light from leaking out. In that case you need something like this:\nhttp://www.uky.edu/Ag/Entomology/ythfacts/4h/unit2/hotm&ult.htm )

That would be an enormous capacitor to be built, and yet the charge of a lighting bolt will vaporize such a huge capacitor, the answer is no, it not possible..☺

The energy from the light is absorbed into the walls, etc.  If you could create a room that had everything in it 100% reflective, then the light would continue to exist.  But, you wouldn't know this, because you are not 100% reflective, and you would absorb the light.

The moment you hit the speed of light, time would stop for you, so it would be pretty hard (impossible) to turn the darn lights on!\n\nSaid another way, as you approach the speed of light, the outside observer sees you slowing down; when you hit the speed of light, it would take the observer an infinite amount of time to see any change in your state.\n\nNow, suppose you left your headlights on the whole way, what would everyone see?\n\nAs you approached the speed of light, the light is still reflecting off the objects around you, so the observer, and you, continue to see the reflected light. Once you hit light speed, however, the energy transfer required to turn heat into light wouldn't occur, so no one would see the photons. Of course, since you're traveling at the speed of light at that point, everyone would see you hit the object.\n\nOr this way... the light leaving your headlight changes it's frequency in proportion to the speed you're moving, once you hit light speed, the light would become matter! Of course, the wave packet that is light + your car wouldn't are too much, since time wouldn't exist for you anymore.\n\nHave a nice trip!

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?

There are 2 possible scenarios ::\n1) Mirror in your hand ::\n   Yes definitely u'll be able to see ur image as mirror is\n   also travelling at the same speed as u & so u both are\n   stationary with respect to each other.\n2) Mirror is stationary ::\n   No, because ur eyes wont be able to adjust to such a fast\n   transition.

use as a mirror, when it's switched off
