Rainbow in the Dark

[Queso]

One night I was playing guitar in a very vast field,

One of those nights where you know it's a full moon.

There were many bats around,

You could see them in the moonlight.

Anyway,

I looked over, above the city and there was a rainbow.

Not a hallucination, an observation.

:)

Previous to that, I was unaware that rainbows could occur from moonlight, which is reflected sunlight,

with just a Speck of moondust,

For taste.

Anybody else seen a rainbow @ Night-time?

Not until just now, but that's got to be one of the most beautiful things I've ever seen. Thanks Orby! :hihi:

wow, great photograph.

Is that a long exposure shot on the full moon?

Explanation: Have you ever seen a moonbow? Just as rainbows are lit by the Sun, moonbows are lit by the Moon. Since the Sun is so much brighter than the Moon, sunlit rainbows are much brighter and more commonly seen than moonbows. Pictured above is a moonbow stretching over Salt Pond Bay in St. John, Virgin Islands. Sailboats are visible on the left. To bring out the moonbow, an exposure of 30 seconds was needed, making the picture appear as if it was taken during the day. Since moonlight is itself reflected sunlight, the colors are nearly the same. Both rainbows and moonbows are created by light being scattered inside small water droplets, typically from a nearby rainfall. The raindrops each act as miniature prisms, together creating the picturesque spectrum of colors seen.

I believe that the first person to see a rainbow in the dark was Ronnie James Dio.

and why do both rainbows and moonbows take perfect circular paths? if its from falling rain would you not expect the effect to be a bit more scattered?

[Jay-qu]

Why does the light dispersed by the raindrops form a bow? The answer to

this involves a bit of geometry. First of all, a rainbow is not the flat

two-dimensional arc it appears to be. It appears flat for the same reason a

spherical burst of fireworks high in the sky appears as a disk-because of a

lack of distance cues. The rainbow you see is actually a three-dimensional

cone with the tip (apex) at your eye. Consider a glass cone,the shape of

those paper cones you sometimes see at drinking fountains. If you held the

tip of such a glass cone against your eye, what would you see? You would see

the glass as a circle. Likewise with a rainbow. All the drops that

disperse the rainbow's light toward you lie in the shape of a cone-a cone of

different layers with drops that deflect red to your eye on the outside,

orange beneath the red, yellow beneath the orange, and so on all the way to

violet on the inner conical surface. The thicker the region containing the

water drops, the thicker conical edge that you look through, and the more

vivid the rainbow.
