Title: Misleading post - there is a finite number of colours?
Post by: McQueen on 10/09/2020 06:42:13
What the OP  states is true, all colours are quantized, which means that only whole photons of a particular frequency and colour can be emitted by excited electrons. Yet, there is another aspect of light that is being ignored and this is that light of various frequencies can combine together, just as radio frequencies do, to get a whole new array of frequencies and colours or as sound waves mix to give an almost countless array of sounds. For instance red light can mix with blue and green to give different shades of orange and so on.  Light of different frequencies can mix because they are very close together frequency wise. The same thing applies to sound and radio-waves, for instance, it would be difficult to mix sound wave frequencies of 10Hz with 20,000 Hz and so on.  This is also the reason that photons (light) are considered to be electrically neutral, the difference in energies and frequencies between optical photons and electromagnetic (magnetic) radiation is so great, that for all purposes it does not exist and photons can pass through a magnetic or electromagnetic field without being affected at all.

No, it's not.
That's not the only problem with your post.

No problem, but I thought that Newton had established in 1666, which is quite some time ago, that different frequencies of light can combine to give new colours.  In the same way the Second world war had proved that only radio transmissions very close to the frequency that had to be jammed  were effective in the jamming process. Lastly, by extension of this observation, it follows that light is electrically neutral because its frequencies are not affected by magnetic (electromagnetic) “fields.”  Light does combine with light, but not with radio waves, which after all are also electromagnetic radiation.  If this is a new theory, well and good; More joy to me,  right?

Nobody disputed that; why raise it?

It doesn't follow from that.
It follows from the fact that light has no charge.
Light does combine with light, but not with radio waves,
Actually, it can.
If this is a new theory,
No.
It's a collection of errors and non-sequiturs.

Incidentally, brown is a well defined colour, but it's not characterised by a wavelength or range of wavelengths.

I think you better clean your glasses, maybe some dirt got onto them and it is tinting your view of things. What I said was ‘light’ does not interact with radio-waves, which are a type of electromagnetic radiation, not that ‘light’ does not interfere with electromagnetic radiation.   Further if you insist on posting misleading information, as seen in your quotes, kindly provide some references.

If I was postign misleading information by quoting you, that's only possible if you posted misleading information in teh first place.

To clarify things:
You said

Light does combine with light, but not with radio waves
And I pointed out that light does combine with radio waves.
