Could that be because it doesn't?

Go argue with the scientists.

Some even assumed I was being sexist! And I'd like
to have a nickel for those that thought it was wrong
about radio waves being light energy, as was
discovered by Herz.

Radio waves, like light, are part of the electromagnetic spectrum.

Radio waves are light, too.

Many didn't even know that
the whole EMR Spectrum is the spectrum of light

No it isn't. Light is PART of the electromagnetic spectrum.

I know it must sound funny to you to hear someone
say that radio waves are light, but they really are,
Bob. James Maxwell, the famous scientist, predicted
the existence of radio waves. Along came Heinrich Hertz,
the famous German scientist, and he proved the existence
of radio waves in the late 1880's, and that they had
electromagnetic properties. But then he took a simple
oscillator and timed the waves, and he found out that
they are indeed a form of light energy, as they have the
same velocity of light. "This proved that radio waves
were a form of light!" The unit of measure of the
wavelength of radio waves is named after Hertz.

energy. It's divided into visible light and invisible
light.

Part of the UV and IR range is considered light because some
animals/insects do see it.

Yes, that's true. Some organisms can detect some
of the radiations that our eyes cannot see. Dogs can
hear sounds we can't hear. And yes the IR and the UV
are not visible to us, but we can certainly see what
they do and know they are there when we microwave
a cup of coffee to heat it up, or when we get a
sunburn. But just because our eyes only see a portion
of the light spectrum, doesn't limit the spectrum. Some
of it, invisible to us, does exist beyond the UV and IR.
We can't see X-rays, Cosmic rays, gamma rays, etc. but
that doesn't mean that they are not there as radiations
(of light).

It's all the same energy but with different
wavelengths.

True, but the word "light" is limited to only part of the spectrum.

Well, Bob, you can refer only to visible light as light...
and sometimes there is a purpose for doing so if you
are speaking only of visible light, but really and truly,
the title of it all is properly called....
"Electromagnetic Radiation Spectrum of Light."
See for yourself in this web page, and look at the
title:

"When we refer to the whole spectrum of light, we can call
it electromagnetic radiation...."
"What is Electromagnetic (EM) Radiation?" [also called EMR]
"Although it would seem that the human eye gives us a pretty
accurate view of the world, we are literally blind to much of
what surrounds us. A whole Universe of color exists, only a
think band of which our eyes are able to detect; an example of
this visible range of color is the familiar rainbow (an example
of a 'spectrum'). The optical spectrum ranges in color from reds
and oranges up through blues and purples. Each of these colors
actually corresponds to a different energy of light. The colors
or energies of light that our eyes cannot see also have names
that are familiar to us. We listen to radios, we eat food heated
in microwaves, we have X-rays taken of our broken bones. Yet
many times we do not realize that radio, X-ray, and microwaves
are really just different energies of light!"

All light, both visible and invisible, has a double action,
one, it is composed of particles called photons, and two,
it has a wavelength. That is proplerly called particle-wave
duality. X-rays, for example have high energy photons, and
so X-rays act more like photons, but radio waves have
weaker low photon action, and behave more as a wave
behaves. But they still are all part of the light spectrum.

The people in here claiming that this
was not true, visibly had been confused by the fact
that the particular entity within the EMR Spectrum
had two speeds to present. One being the forward
speed at which they travel vs. the frequency of their
wave lengths, which is a different measure.

That didn't make sense.

The term "velocity," describes the forward speed. As you
know, photons of visible light take 186,000 miles per
second to reach us. But each of the things that compose
the spectrum, also has a sort of vibration which determines
which group it belongs to. That vibration produces the
wavelength. It's sort of an up and down or back and forth
movement within the velocity. Suppose you have a family
in a car and a little boy in the back seat that is exicted about
his car ride..so much so that he is bouncing up and down
on the seat while watching the scenery go by. He is both
being propelled forward by the speed of the car, while
simultaneously bouncing up and down at a different rate
of speed of course, than the forward speed of the automobile.
