…The electromagnetic (EM) spectrum is …types of radiation … as a group. Radiation is energy that travels and spreads out as it goes– visible light …. from a lamp….or radio waves .. or from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves, infrared and ultraviolet light, X-rays and gamma-rays. Hotter, more energetic objects and events create higher energy radiation than cool objects. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like X-rays and gamma-rays. Here are the different types of radiation in the EM spectrum, in order from lowest energy to highest:

Radio Radio: …this is the same kind of energy that radio stations emit into the air …to capture and turn into your favorite Mozart, Madonna, or Coolio tunes. But radio waves are also emitted by other things … such as stars and gases in space…
Microwave Microwaves: … will cook your popcorn in just a few minutes! In space, microwaves are used by astronomers to learn about the structure of nearby galaxies, including our own Milky Way!
Infrared to UV Infrared: we often think of this as being the same thing as ‘heat’, because it makes our skin feel warm. In space, IR light maps the dust between stars. Visible:…this is the part that our eyes see. Visible radiation is emitted by everything from fireflies to light bulbs to stars … also by fast-moving particles hitting other particles.

Ultraviolet: we know that the Sun is a source of ultraviolet (or UV) radiation, because it is the UV rays that cause our skin to burn! Stars and other “hot” objects in space emit UV radiation.

X-ray X-rays: your doctor uses them to look at your bones and your dentist to look at your teeth. Hot gases in the Universe also emit X-rays .
Gamma-ray Gamma-rays: radioactive materials (some natural and others made by man in things like nuclear power plants) can emit gamma-rays. Big particle accelerators that scientists use to help them understand what matter is made of can sometimes generate gamma-rays. But the biggest gamma-ray generator of all is the Universe! It makes gamma radiation in all kinds of ways.

A Radio Wave is not a Gamma-Ray, a Microwave is not an X-ray … or is it?

Across the EM spectrum
Radio waves, visible light, X-rays, and all the other parts of the electromagnetic spectrum are fundamentally the same thing, electromagnetic radiation.

We may think that radio waves are completely different physical objects or events than gamma-rays. They are produced in very different ways, and we detect them in different ways. But are they really different things? The answer is ‘no’. Radio waves, visible light, X-rays, and all the other parts of the electromagnetic spectrum are fundamentally the same thing. They are all electromagnetic radiation.

Electromagnetic radiation can be described in terms of a stream of photons, which are massless particles each traveling in a wave-like pattern and moving at the speed of light. Each photon contains a certain amount (or bundle) of energy, and all electromagnetic radiation consists of these photons. The only difference between the various types of electromagnetic radiation is the amount of energy found in the photons. Radio waves have photons with low energies, microwaves have a little more energy than radio waves, infrared has still more, then visible, ultraviolet, X-rays, and … the most energetic of all … gamma-rays.

Across the EM spectrum
The electromagnetic spectrum can be expressed in terms of energy, wavelength, or frequency.

“Actually, the electromagnetic spectrum can be expressed in terms of energy, wavelength, or frequency. Each way of thinking about the EM spectrum is related to the others in a precise mathematical way. So why do we have three ways of describing things, each with a different set of physical units? After all, frequency is measured in cycles per second (which is called a Hertz), wavelength is measured in meters, and energy is measured in electron volts.”

“The answer is that scientists don’t like to use big numbers when they don’t have to. It is much easier to say or write “two kilometers or 2 km” than “two thousand meters or 2,000 m”. So generally, scientists use whatever units are easiest for whatever they are working with. In radio astronomy, astronomers tend to use wavelengths or frequencies. This is because most of the radio part of the EM spectrum falls in the range from a about 1 cm to 1 km (30 gigahertz (GHz) to 100 kilohertz (kHz)). The radio is a very broad part of the EM spectrum. Infrared astronomers also use wavelength to describe their part of the EM spectrum. They tend to use microns (or millionths of meters) for wavelengths, so that they can say their part of the EM spectrum falls in the range 1 to 100 microns. Optical astronomers use wavelengths as well. In the older “CGS” version of the metric system, the units used were angstroms. An angstrom is equal to 0.0000000001 meters (10-10 m in scientific notation)! In the newer “SI” version of the metric system, we think of visible light in units of nanometers or 0.000000001 meters (10-9 m). In this system, the violet, blue, green, yellow, orange, and red light we know so well has wavelengths between 400 and 700 nanometers. This range is only a small part of the entire EM spectrum, so you can tell that the light we see is just a little fraction of all the EM radiation around us! By the time you get to the ultraviolet, X-ray, and gamma-ray regions of the EM spectrum, lengths have become too tiny to think about any more. So scientists usually refer to these photons by their energies, which are measured in electron volts. Ultraviolet radiation falls in the range from a few electron volts (eV) to a about 100 eV. X-ray photons have energies in the range 100 eV to 100,000 eV (or 100 keV). Gamma-rays then are all the photons with energies greater than 100 keV.

Why Do We Have to Go to Space to See All of the Electromagnetic Spectrum?

Electromagnetic radiation from space is unable to reach the surface of the Earth except at a very few wavelengths, such as the visible spectrum, radio frequencies, and some ultraviolet wavelengths. Astronomers can get above enough of the Earth’s atmosphere to observe at some infrared wavelengths from mountain tops or by flying their telescopes in an aircraft. Experiments can also be taken up to altitudes as high as 35 km by balloons which can operate for months. Rocket flights can take instruments all the way above the Earth’s atmosphere for just a few minutes before they fall back to Earth, but a great many important first results in astronomy and astrophysics came from just those few minutes of observations. For long-term observations, however, it is best to have your detector on an orbiting satellite … and get above it all!

What is a Wave Front? October 8, 2006

wave front

is an imaginary surface representing corresponding points of a wave that vibrate in unison. When identical waves having a common origin travel through a homogeneous medium, the corresponding crests and troughs at any instant are in phase; i.e., they have completed identical fractions of their cyclic motion, and any surface drawn through all the points of the same phase…

“The important words in the above are the corresponding crests and troughs at any instant are in phase.”

“Now imagine an onion where – in each separate layer of onion skin – the transverse waves, making up that particular skin, have their crests and troughs all in phase at the same instant.”

This onion phase image, then, is the best picture of a scalar, standing wave that anyone will ever give you.

Oh yes, a scalar wave, of necessity, must always be a standing wave….Essentially, standing waves are not absorbed, by the surroundings, while the rest are.

And this is the secret to the construction of our universe where all particles were/are created as scalar, standing waves.

“Why this happens we don’t really know…..It’s hard to envisage an infinite universe but it is not hard to envisage an infinite frequency spectrum and this is what I think we have, full of various frequency waves of all sorts.”

“Every so often just like piano keys, at certain points in this frequency spectrum, scalar standing waves are allowed to develop and remain and are NOT absorbed by the surrounding wave cacophony.”

“These, then, are all our permanent particles…. Now imagine an onion where – in each separate layer of onion skin the transverse waves, making up that particular skin, have their  crests and troughs all in phase at the same instant. This onion phase image, then, is the best picture of a scalar,  standing wave that anyone will ever give you. Oh yes, a scalar wave, of necessity, must always be a standing wave.  Essentially, standing waves are not absorbed, by the surroundings,  while the rest are.”

…an important property…of the wave structure of the universe = the energy exchange mechanism…. by definition a STANDING WAVE is not absorbed or exchanged – otherwise it is no longer standing.

“Exchanges are always resonant – like two piano strings of the same tone. That is about all there is to exchanges and non-exchanges….the Universe is the way it is because it only takes on the wave structures allowed by the rules?The rules of waves in space.”

“The Universe is very simple because ALL the rules are contained in Principle I (the Scalar Wave equation) and Principle II (medium density), and of course ‘space’ itself. These rules create the Atomic Table and that leads to ALL the millions of different metals/atoms/molecules/compounds. We can’t ever calculate them all, but the rules are so simple that we understand how it works.”

“You could almost say “We are all made of onions!”…We understand the Universe. QED…The only thing we don’t understand is ‘space’the wave medium. What is it? How did it get there? Why does it have these wave properties?”

 …”Why do people keep on speculating on useless other things, discrete particles that don’t exist, math that applies to nothing, when ALL their questions are answered by the Wave Structure of Matter? Especially when the real remaining problem is SPACE!”…Most people play an endless gamble hoping that an old idea they once had will turn fruitful. “
“…Standing wave resonances exist in an infinite sea of quantum waves.”
