How can we trap light in a basic container?

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 )

Ok, this is how you do it.  You need to have the following items: A coil of copper wire, a barrel shaped magnet, a tube, and a bulb.  Take the tube, and this could even be a paper towel cardboard center, and wrap coils of wire around the outside of the tube as many times as you can.  This should cover the outside of the tube.  Now, take the two ends of the wire and connect them to the + and - of the bulb that you will be using.  You must then place the magnet (a barrel magnet is best, but any will do.  The stronger the better) inside the tube, and cover both ends of the tube.  Now, as long as you are shaking the tube lengthwise, and the magnet slides up and down inside the tube, the bulb will shine.  To make a more practical flashlight, you could do one of two things.  Either have an electrical storage device that will hold the charge so you don't have to keep shaking it, or you could rig something up that will keep the magnet moving inside.  Either or both will work.

Smoke or fog will work.  There are also 100mW red lasers out there (wickedlasers.com should do the trick) that have some visibility in daylight, but this always depends on there being something (even the tiniest amount of dust) in the air to scatter off of.

If u want something easy u can make a rpleca of the solar system. U can by those foam balls and spray paint them. Or u could do an experiment on two plants giving one sunlight and no light to the other. But still feed and water them.

make a solar cell that will light up a lightbulb. Figure out how by doing an internet search

put the counter closer cos alpha raysonly travel a short distance...maybe that will work?... \n\nor get something that will alter with radiation... i think there a material that changes colour when hit with radiation....\n\nOOOOOOOOOrr... get something that emits a longer range radiation ray when the alpha partiles hit it...that way u can get a good approx of the count

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.

I think what you might be looking for is on Compfused.com\nThey had a tutorial about how 2 make little lights.\n\nOkay I found a site that tells you how 2 make led throwies(that is what they call them)\nGo 2 www.instructables.com they r right there.\nI understand this might not be what you r looking for but it might help:)

Don't forget that your samples must be small and THIN (flat). If the sample is too big/thick then no light will pass through to the lenses.\nMost things are best viewed after mounting them in a drop of water under a cover slip.\n\n1. Crystals of salt, icing sugar, etc.\n2. Fibres of cotton, wool, synthetics, string, etc.\n3. The torn edges of paper.\n4. The individual dots of colour from non-glossy pictures. You will probably have to add a bit more illumination from above the sample for this by shining a light onto it (e.g. desk light).\n5. Leaf 'skeletons'.\n6. Living leaves - from a potted plant (e.g. a 'spider plant') bend the leaf and clip it between two slides. (Additional top illumination needed.)\n7. The thin 'skin' from between the 'leaves' of an onion (onion epidermis).\n8. The edge of a razor blade or sharp knife (with top illumination).\n9. Strands of spider webs.\n10. Dust.\n11. By gently using a potato peeler you can make thin sections of all sorts of plant parts. Usually only the very edges of these sections are suitable for viewing. You might like to stain plant samples with a drop of iodine (use instead of water) under the cover slip.\n12. If you have a wood-plane then make thin samples of different types of wood.\n\n(P.S. Forgive my UK spelling)

Throw light . \nwhy, doesn't the place get any sunlight.

The light is reflected

reduce your light on the screen if no change see an optician they will advise you

Try one of those kits that come with a blue-light attachment.  You can find them at some drug stores.  You'll see a significant difference in about 15 minutes.  They cost about $25.00.

Say you shine a flashlight into a mirror. Then put a mirror behind the flashlight and remove the flashlight. Given that the 2 mirrors are exactly parallel, will the light just bounce back and forth forever? No - the light travels in waves and each time it reflects back, some of the light is not hitting the mirror exactly at 90 degrees and is reflected off on an angle. The light will reflect away and eventually dissipate completely. \nIf you try to trap light in a box, as it bounces off the walls inside, it will dissipate into energy (heat). The temperature of the inside of the box will raise - but just infintestimly so.\nRemember all of this will take place at the speed of light.
