h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I'm not a physician but only someone very interested in the possibility of reproducing a rainbow with artificial light. I've heard from a teacher in physics that there has been a video shown on the bbc where actually they did reproduce the right conditions and created a rainbow in studio.
Can someone help me to find this information? I thank you very much.

That shouldn't be difficult to do. All you need is lots of small water driplets in the air and a light. You'll see a rainbow if the geometry between you, the water cloud and the lamp is correct. The angle should be close to 90° or so:

water
xxxxx -------- light

I've seen a rainbow in my garden which was produced by the garden sprinkler (sp?) which was set up to spray the water upwards, and the sun shining from the side

Hey Bossel, long time no see, eh?

What about awü? seen him?

Well... What about this entry? Still wip? I think it's quite complete now - maybe we should just add the link to those newer entries on wave-equations... (I'll look that up tomorrow)

See you...

HELL

Oh yeah, atm *everything* is a W.I.P. to me. I don't know where my head stands (nice Genglish, eh?) and I think there *was* something left that I need to fix or amend

you say 'wave equations'? ugh! where's that?

Hi Bossel and Hell!

Are you going to put this through PR? It's a fantastic entry.

Oh, thanks for the laurels

Yes it's moving towards PR -- albeit slowly because at the moment Hell is moving (house) and I haven't got around to find that bug somewhere in the THz gap. Somewhere around there, the decimal places are out of order



say, how did you find that piece anyway?

OK ... I look forward to seeing it in PR

I was looking up to see if there was an entry on "photons" for an entry I was thinking of writing, and found it!
