[BBC] - 'Quadruple rainbow' caught on film for the first time

post #1 of 26
Thread Starter 
Quote:
Scientists have captured the first image of a "quaternary" rainbow - the fourth rainbow caused by the bending of light through water in the air.

This refraction frequently creates a visible second rainbow, but until now, no one had caught sight of the fainter third and fourth arcs that the process creates in a different part of the sky.

The first tertiary, or third, rainbow has only just been caught on film.

Digitally enhanced pictures of the two effects appear in Applied Optics.

Unfortunately, the pictures are not as striking as more familiar images of double rainbows - and some image processing was the only way to make the arcs visible at all.

That is principally due to the fact that the tertiary and quaternary rainbows are by definition far fainter than their more familiar cousins.

Too bad it's not more easily seen. Bet it would be quite a sight. smile.gif
