i though i understod light, but this is wird, maybe
i forget the explanation, her it comes

our eyes can detect light EM in the visible spectrum,
say lambda 700nm to 400nm, which is very nice

wait a minute, lets an object be only visible outside the
visible spectrum, say UV eller IR, so we cant see it

wait a while, we make it simple, suppose that this
object lay on your table, you cant see it so it is
invisible, do not confuse, it is not transparent, because
if it were then you could see it, you don see anything on
your table, your table seems empty

now, if you drag your hand on your table will you sense it,
will you touch and detect its shape?

would this invisible object be existing?

you cannot say that light is wave and/or particle

light is much more than that

thanks for your feedback, but your links are EM links, which
is an oversimplification

Maybe this is more your speed:

Now, does not the prize to Einstein imply
that the Academy recognised the particle
nature of light? The Nobel Committee says
that Einstein had found that the energy exchange
between matter and ether occurs by atoms emitting
or absorbing a quantum of energy,hv .

As a consequence of the new concept of light quanta
(in modern terminology photons) Einstein proposed the
law that an electron emitted from a substance by
monochromatic light with the frequency has to have
a maximum energy of E=hv-p, where p is the energy needed to
remove the electron from the substance. Robert Andrews
Millikan carried out a series of measurements over a
period of 10 years, finally confirming the validity of this
law in 1916 with great accuracy. Millikan had, however,
found the idea of light quanta to be unfamiliar and strange.

The Nobel Committee avoids committing itself to the
particle concept. Light-quanta or with modern terminology,
photons, were explicitly mentioned in the reports on
which the prize decision rested only in connection with
emission and absorption processes. The Committee says
that the most important application of Einstein's photoelectric
law and also its most convincing confirmation has come from
the use Bohr made of it in his theory of atoms, which explains
a vast amount of spectroscopic data.

Pure diamond has no emission bands in the visible light region. Do
diamonds exist?

You seem to be entertaining the notion that your
furniture vainishes when you turn off the lights
in the room. I suggest you design an experiment
to test your notions.

Amazing how you take the word of some crap on the internet
and reject the wonderful wisdom of the genius Einstein, ****head.

Dear David

is been said that transparency means visible, and
is visible indeed

imagine complet invisible
