All is energy.
Existence = dynamic interactivity.
Vacuums do not exist, in the absolute sense. They are theoretical, describing non-existence. Even space has a temperature, ergo it is not absolutely empty.
There is no absolute zero/nil state.
Vacuums or voids actually refer to levels of interactivity that fall beneath organic perceptivity - even aided by technologies - or states of chaos, where no measurement is possible other than as a temperature measuring chaotic energies, or energy patterns too subtle or too complex to be perceived - background radiation of chaotic interactivities are often confused for complex energy patterns because both are imperceptible without technologies, in the case of complexity, or not at all, as in the case of chaotic energies.
Chaos = lack of pattern - absence of order.
Chaos cannot be perceived nor measured directly, but only through its effect, i.e., interactions, with order.
Chaos, by its nature, is inconsistent and random, and so may randomly emerge as order, and then fall back into its chaotic state. this chaotic behaviour makes it imperceptible and unmeasurable.
Causality, i.e., interactivity = attraction/repulsion.
Harmony between patterns describes a reduction of fiction, experienced as attraction - reduction of resistance.
Most of this doesn’t mean anything, as far as I can tell.
It seems to me that the best way to find answers for all your physics curiosities is for you to roll up your sleeves and study physics. Have you considered that? You can learn it all for free you know. I can even help point you in the right direction if you like.
Please point me to learning it the correct way first, rather than teaching crap I have to unlearn on my way to the right way. If it exists.
There’s no fast track to learning physics that I know of, you gotta start at the bottom.
Here’s a free course on high school physics
khanacademy.org/science/high-school-physics
Once you’re finished with that, next is calculus and Newtonian physics, and then if you’re really dedicated, you’ll have the tools to learn relativistic physics.

What is the period of a wave at the frequency of 1 Hertz?
What is the wavelength of a wave at the frequency of 1 Hertz?
What is the wavelength of a wave at the frequency of .5 Hertz?

A second… 1 hertz, being 1 second long.
Right, the period of that wave is 1 second of time. You just said what Flannel said nobody says, proving him wrong…
1 cycle per second
2 cycles per second.
2 cycles per second is the frequency of 2 Hertz. The period per cycle is .5 seconds.
There is no getting around it and why the speed of light is 299,792,458 meters per second. Because that is a wavelength of 299,792,458 meters, and a frequency of 1 Hertz, which means the speed of light is 299,792,458 meters per second.
Ahhhh… I need to re-swot-up, on the matter of all things ‘frequency’. 
Fun fact: “The entire array of radiation observable to the human eye is only about 0.0035 percent, otherwise known as visible light.”
aka
…the invisible electromagnetic spectrum being the elusive ‘dark matter’ which could be what holds everything in its place, in space.
Frequency is simply “cycles per second”, and instead of saying “27,185,000 cycles per second” we say a frequency of 27.185 Mega Hertz, which is simply 27.185 million Hertz, or for most regular folk…channel 19 on CB… 
Visible light is just a portion of the spectrum of electromagnetic radiation, measured by frequency, which is how many cycles per second, and the wavelength which is the distance of each cycle.
Simples! 
PS…There is no wiggle room for such BS as “Length Contraction” or “Time Dilation” as some people that fudge stuff would have you believe…
Thanks for the clarification… Science lessons are all coming back to me, flooding my brain with its hubris.
Length contraction exists… in Inkblot Cartoons from yesteryear. 
With regard to time dilation, the only thing that could permanently change the frequency of light, is if the condition/s for setting that frequency changed… which may well happen in the very-distant future as the universe evolves and therefore changes, over time.
Can Science tell when electromagnetic waves came into being?
Immediately. But science also doesn’t agree with the stuff you were agreeing with motor daddy about so it maybe doesn’t matter much what science thinks. You guys know better.

I came across only one article, re. my inquiry.
“There have been many models in this direction, most of which rely on new physics, and are therefore not convincing,” comments George Field of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, US.

You asked about electromagnetic waves. Photons are electromagnetic waves. Photons existed immediately.

Did you not mean photons when you said ‘electromagnetic waves’?

Some interesting info…
Investigation into electromagnetic phenomena began as early as 5,000 years ago. There is evidence that the ancient Chinese, Mayan, and potentially even Egyptian civilizations knew that the naturally magnetic mineral magnetite had attractive properties, and many incorporated it into their art and architecture.
I would suspect even earlier than that… the much-earlier lost/buried civilisations of a prior antiquity i.e. lost technology.
…all objects, including human bodies, emit electromagnetic radiation. The wavelength of radiation emitted depends on the temperature of the objects. Such radiation is sometimes called thermal radiation. Most of the radiation emitted by the human body is in the infrared region, mainly at the wavelength of 12 micron.
…the 12 micron crew/clique/gang 
Without the electromagnetic force, atoms and molecules would never form. Electromagnetism is the force exerted by charged particles on one another. Electrons and protons are oppositely charged particles that react to both electric and magnetic fields.
So the ‘glue’ that holds everything together/the catalyst, to this conversion/the cause, of this effect^
I meant the electromagnetic radiation spectrum of all light, but your reply is perfectly pertinent too…
The inflation period postulated instead of the singularity with quantum mechanical arguments has no photons.
As the universe cools quarks gluons electrons etc appear in a plasma soup , and before symmetry breaking all particles have zero mass, i.e. are photon like. What will develop into photons are the four gauge bosons which are all photon like because their mass is zero.
electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. Although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies.
Now… what dictates the formation of which light-wave forms, when and where.
