It has no medium. If it oscillated longitudinally in a physical medium it would produce sound. It is transverse and is an EM wave therefore no sound.

Consider the following:
Light is just the sun screaming at your eye ears.

Does light create friction?

Synesthetic pls.

It's frequency is in terrahertz,
Sound frequency is in just regular hertz lol.
So it's like 37 octaves above the limit of human hearing (octave is a doubling of frequency.)

What you are perceiving as vision is your brains interpretation of light frequency.
What you hear is your brains interpretation of soundthey recently discovered dogs and cats have retina chemicals that are sensitive to electromagnetic frequencies (megahertz kilohertz etc.)

So when you look at light you are "hearing it"
Humans seem to be calibrated for about 8 octaves per input.
ABCDEFG (7natural notes per octave, 12 if you include sharps and flats, natural are white keys, sharps and flats are black, so 12 notes per octave, 7 octaves, 88 or so keys on a standard keyboard.

Light works exactly the same.
ROYGBIV, 7 colours,

Now this is where it gets cool.

A chord is made of three mathematically compatible notes, (explanation takes pages and pages so I won't expand, it's called "music theory")

Like typically the first, third and fifth interval of these notes.
Like C E G is C major. C Eflat and G is C minor, as it has a "flatted third"

Anyway white light is Red Green and Blue.
So it's a chord. Just like in music.
These sciences work exactly the same.

Music theory is brutally difficult and complex. And way harder than quantum physics, but it's the most powerful science.
I use it in organic chemical engineering.
It's used in analytical chemistry if you are NMRing some unknown samples, it just used sympathetic resonance.

And if you interpret the wrong input, like "tasting sound" or " "hearing colour" that's synthesis.

Sound is due to pressure waves, and since EM waves are able to exert pressure I’d say yes, but obviously it would be very quiet since there’s such little pressure. So I’d say if you had a super high amplitude radio wave then maybe

I think it does. When I turn on my light switch I hear a "click" as the light comes out

Except it doesn't look good like a chord sounds good.
If you take pure wavelengths of rgb then it's not real white I'm pretty sure white light has all wavelengths, not just spikes. Imagine if you could write music using light. Or you could call a painting visual music but that would just be dumb.

You realize there are other tuning systems than equal temperment, right?

Yes, I'm sure music theory is much harder than quantum field theory.
How much time do the world's fastest supercomputers spend on lattice approximations of music theory?

>>11404698
it's so hard that you can't even compute it.

>>11404745
No, it's some trivial nobody even tries.

This has to be bait. Are you confusing general wave mechanics with music theory?

>>11401800

Not proven.

>>11405320
Mathematically speaking its medium is the electromagnatic field, whatever that may be in reality.

nice post

I not sure what you mean with that, do you mean that their eyes can percive lower frequencies in the Mhz and khz range? that seen way too low to be true, do you have a source for that? its sound like its just an in vitro responce of their retina cells and not that they can actually see those frequencies (this would mean the whole visual chain including the brain)

TV are based on RGB color theory...the movies look quite good to me, I dont have a problem with white reproduction

>>11405302
nah, he's just comparing complexity, although I think that comparation was too "out there"

Wrong.
