The colour of light?

[NickK]

Just thinking about light.. daydreaming out the train window - just musing ideas..

What if something could go faster than the speed of light.. the displacement in front of the quanta going the speed of light? We no.. but the front of the quanta "wave" always goes backwards from the forward plane travelling at the speed of light. How would extra energy be mopped up if it's travelling at the speed of light.. electromagnetic spin? where the excess energy causes the quanta/photons to spin (just like a motor).

Now if light span, that is the quanta of photons spun at a given frequency.

When the quanta are created, if the forward velocity cannot be beyond a constant (ie 'c') then electromagnetic spin occurs due to the excess energy. That is - if you fired a bullet at C with no additional energy, no spin would occur, however all conversions we see have excess energy and the bullet has additional energy but cannot be accelerated beyond C. Hence the energy is converted to spin. The higher the energy, the closer the incident to C is, resulting in a faster spin.

Now i think every way we have to create light generates too much energy.. creating spin..

The electromagnetic spin is then directly related to the starting energy minus the energy required for the speed of light. So the higher the energy, the faster the frequency cycle.

It would explain polarisation possibly..

Hmm.. no logical proof.. any thoughts?

one problem is if energy excess caused spin speed in excess of c itself, then what happens or do we have another constant

What happens when the spin approaches C

Great minds

When electron spin was first proposed in the 1920s it was quickly pointed out that it would imply the surface of the electron was moving faster than light. So it was quickly concluded that quantum spin isn't the same as what the Earth or a spinning top does, and elementary particles aren't like little ball bearings. So trying to reason about quantum spin on the basis of our familiar notion of spin doesn't get very far.

A key feature of quantum spin is that it is (as the name implies) quantised. You can't make an electron or photon slow down or speed up in its spin: either particle can have one of two values (termed "up" and "down") in a given direction.

You're right, though, spin explains polarisation.

The colour is - Octarine.

Actually it was this point about faster than the speed of light that started the whole things, leading to displacement (ie the surface spinning) being faster.

Also the part about changing of colour - that is changing wavelength (ie not a filter etc and once spinning can't be accelerated or slowed).

All this was started by the train going past a set of rail arches.. i.e. looking a bit like a chain of, what I was terming, quanta.. not looked into quantum spin etc so I may have a look.
