How do you define “absolute white light”?
[…]


The absolute white light is the original light, cast from atoms before
contaminated with filters of matter.


Atoms *are* matter by any scientific definition of this rather non-
scientific term, so there is nothing to contaminate. Light is not exactly
emitted from atoms (“cast” is such an obscure term; this is *sci*.ALL), but
from subatomar particles. Precisely, it is emitted when a particle in an
excited state, such as electron, loses energy to revert to a more stable
state (Einstein demonstrated in 1905 that this phenomenon, the photoelectric
effect, is determined by Planck’s constant indeed, thereby laying the
foundations for quantum mechanics; he received the Nobel Prize in Physics
1921 for this discovery in particular).

As regards the color, white, what you are talking about does not exist:
White is the result of *humans’* perception of electromagnetic radiation
that has a sufficient number of various wavelenghts of the visible spectrum
*combined* to activate the photoreceptor cells in the human retina
accordingly. (Therefore, black is perceived as the result of the minimum,
or absence, of *visible* light reaching the photoreceptor cells of a human
observer. So, strictly speaking, black and white are not true colors;
neither are grey tones.)

You can use a prism to confirm this: different colors, that is,
electromagnetic radiation of different wavelength are refracted at different
angles (that applies to *all* EM waves; those outside the visible spectrum
you may be able to feel, e.g. infra-red as heat, but cannot see). Or, if
you do not have a prism, wait for a rainbow to appear or spray water around
on a sunny day to make one.
