Yes light has harmonics, but what we were discussing there is whether harmonics are involved in producing the 2nd and 3rd rainbows. Zix was right, I was wrong.
Sirguess: Yes, I meant within the context of rainbows. All EM radiation has higher harmonics. The circular rainbows around shadows are usually called "glories" and can be seen around your own head if you look into a foggy valley with the early morning sun behind you. This is another trick the bull.... self-help gurus try to pawn off as "empowerment"--they let you "firewalk" the night before, then fake you out at dawn with your "glory".
Rainbows? Harmonics? Man! I'm getting' to like this place more and more everyday. It's good for my soul. Ex, sorry about my comments the other day. No offense intended.
"the visible portion of the spectrum subtends less than a full octave of frequencies"? That went over my head like a shot. Had to get the video and do a stop-action just to get a look at it. I'm still looking at it with a magnifying glass.
And by the way, I ain't walking on no coals just to git a rainbow over my head.
MATILDA, put your money away and lets lock the door. The bar is open!
Seaspray: In music, when you go up an octave, you double the frequency of the sound. So, if you have a 440Hz tone (which is the note "A"), the "A" in the next octave up on the piano will have a frequency of 880Hz. This nifty phenomenon makes all sorts of harmonious musical mixtures possible.
Visible light, on the other hand, only has a range of 400-700nm--not enough to see "chords" or even a harmonic. If we could see just a little farther down into the infrared (800nm), then deep violet (400nm) would be a harmonic of that color.
I was totally unaware of how narrow a band of frequencies we can see. It's got me wondering what it would look like if that weren't the case. I can't even imaging yet what seeing "chords" would be like.
I suppose that harmonies of light, like music, do not necessarily have to double in frequency to harmonize. There are octaves, but there are also 7 basic notes to consider within the octave. Some sound great together without having to double the frequency.
A note with another, just 5 half-steps away (out of 12 in an octave) will get you a good sound. 7 half-steps will too. These are simple, but a blend of frequencies (chords), even within an octave, will produce some sort of resonance.
Jump 11 half-steps and you get a beautiful oscillation (wobble) that you can set time to, though it would take something like 11 more repeated octaves of it before it was clean again. And even by then, it might just sound like a train wreck. I need more strings! Thank God for music software.
In other words, harmony does not just happen when you jump a perfect octave. A 2 to 1 ratio is clean, but a frequency that fits inside 2/3 of an "octave" would sound good over 3 octaves, no?
What about color?
The relationship between primary and secondary colors remind me of chords?
Heerz a thought:
If the frequency of what we refer to as "spirit" cannot be seen because it is beyond the range of our visible spectrum, then it would make sense that there is both higher and lower frequencies of spirit, or maybe: supernatural and sub-natural colors?
Or even sound. We can only hear certain frequencies (even with gadgets). If whatever spirit IS makes sound, would it not be both above and below what we can hear. Not just above.
***
I guess what I am wondering now, is if the supernatural (higher and low harmonics of light and sound) are often regarded as being ONLY higher, or ONLY lower, depending on the slant of one's religious faith, or favorite cosmological model.

Thanks for the poem, Matilda. Did you write it? If not, it would seem that the conversations on this thread happened to someone else before (and they probably have).

Re: Guru dawns:
Funny.
Wouldn't that be like selling glory that's free?

Pretty much. It's like charging people to "teach" them how to walk on hot coals when anyone can do it.

Right. Only a dumb a$$ would fall for such a trick.

I saw a rainbow in the sky
was red and green and yeller
until an agrument ensued
between two other fellers;
was there one or two or three?
did they reflect my shadow?
were their refractions just for me?
or more prismatic laddos?
I thought I better check my books
to see if my brain worked right
and then I thought, oh what the hell...
I'll trust to know what I like
The beauty of the arky hues
all in their proper order
were not hampered by my woeful lack
of knowing what I oughter
so til He comes or til I go
my awe at Nature's high signs
will be free from heady "gotta knows"
and the value placed on my time.
(hic)
Barkeep...another round for my colorful friends...

Zixar,
Does this have anything to do with good vibrations?
I'll second Mike's nomination and move the vote. All those in favor, say Aye. All those opposed, go jump in the lake.
