- Q: looking for light projects
- I may be totally off with this but infinity reminded me of a type of decorative light fixture which was more artsy than a viable light source. The structure was basically a shadow box perhaps 3 inches deep, and in this case it may have been square. At the back of the box was a mirror that fit entirely. Around the inside of the box were what may have been white christmas lights, and the face was glass covered. As I recall the entire structure was painted black. As I'm thinking this however there must have been other mirrors, unless the back of the clear glass front was refelctive to the inside, because what one could see was a series of these lights in a vanishing perspective way.

- Q: is it possible??

- Q: what color of light is best suited for studio design, florescent, halogen or yellow bulbs? Also, which is better? a big single light source with a sharp focus or multiple lights at various positions. which kind of light source gives the best exposure
- i imagine a three-elementary device is a minimum. both a potential %. with heads or 3 monolights. i in my opinion use the Calumet monolights (made by technique of Bowens) and that i have an extra software slave. countless elementary modifiers starting up with smooth bins (one higher, one medium-small), umbrellas (2 silver, 2 white, or 2 convertable), a barn door attachment, clear out holder, and some grids. A snoot is likewise powerful. you ought to get some reflectors and a diffusor. Then get a number of the upward thrust variety microphone stands from a song keep for flags and scrims. in reality, you want one elementary for the significant or key source, one kicker or hair elementary, and one for the historic past. Then use reflectors to fill in the shadows. some extra lighting fixtures should be reachable, too, yet that is the minimum.
- Q: It only lights up about 10 seconds then goes off. The dash board lights goes out too.
- Go check your relay for your headlights, remove and test with a 9volt battery if you have one laying around, it should make a click sound. Look at the bottom of he relay and you'll see numbers, put the 9volt battery on numbers 85 and 86. If you get a click out of it, bam you should be money. Now you might have a computer issue or there is a ground wire loose or a power wire that is touching ground somewhere or haha sorry it could be lots of things, you are having to many amps on that circuit and it pops a internal virtual fuse in the computer which later it will reset itself, or your stalk switch is messed up. Sorry to write so much I know it really dont help much but that's what it could be honestly, oh yeah forgot, do this first, for Sh!T and giggles, check the connection at the light bulb and the headlight bulbs themselves.
- Q: OK FSX gurus, when do I put on which set of lights furing a commercial flight?
- Hello, Beacon Light: Should be turned on right before start up to alert crew of start up. Navigation Lights: On when plane in motion. Strobe lights: When in the air not taxiing. Landing lights: Below 10,000 Feet Cabin Lights: Your decision Taxiing lights: When taxiing. Did I miss anything Respectfully, CRJ700
- Q: does a planet with atmosphere affect the speed of light
- The short answers to your two questions are, no, and, yes. Gravity has an effect on light, because it has an effect on spacetime itself, but it has no effect on the speed of light. A careful distinction must be made here: the speed of light in vacuum is always c, a universal constant. But light, being an electromagnetic wave, its speed can be reduced by passing through a dielectric medium, such as air, water, plastic, glass, etc. The quantity that relativity says is a universal constant is the speed of light *in vacuum* -- this constant is actually not a property of light, but of spacetime itself, and should probably be called, the characteristic spacetime speed, but that's just too big a mouthful. Any particle with zero rest mass will travel at this speed. It's just that, with the neutrino looking like it does actually have a non-zero rest mass, the photon is the only massless particle we know of at present. @ Allen The K: Actually it wasn't Einstein, but Sir Arthur Eddington who proved the 'bending' of light by the Sun's gravity, at the total solar eclipse of 1919, thus vindicating Einstein's General Relativity (GR). A competing theory had predicted twice the 'bending' that GR did. I've put bending in indirect quotes, because, as you and Trouble both acknowledge, light always travels in 'straight' lines -- geodesics -- through (curved) spacetime. So in effect, Sir Arthur was demonstrating the bending, not of light, but of spacetime itself. @ Trouble: You are right, regarding gravity not affecting the speed of light. But the bending of light in passing between media, is not diffraction, but refraction. Also, this has nothing to do with black hole evaporation (BHE); refraction is a non-quantum phenomenon, while BHE is a manifestation of an effect that is very much quantum in nature -- vacuum fluctuations, which are a consequence of the Heisenberg Uncertainty Principle.
- Q: i'm just curious if light is a matter...
- Light is energy and energy is matter. They are apparently inter changeable remember E=MC2.
- Q: lighting retrofits program For School Associations?
- The lighting retrofit program helps owners and leaseholders of commercial and industrial facilities upgrade light fixtures and lighting controls to energy.
