This one chart pulls it all together quite well.

It was originally meant to be a big wall poster,

so you might use a browser screen magnifier or glass to see it better.

 

WHAT IS FREQUENCY?

It is how often a given event (change from low to high and back, cycle) happens in 1 second, (also hour, day...etc).

For ElectroMagnetic (E-M) waves, we use the second as the base time.

Frequency and Wavelength are reciprocals.

1/F=W  1/W=F

 

Long ago, the unit of measurement was CPS (Cycles Per Second).

That changed in the 1960s, CPS was renamed Hertz (not the car company)

after Heinrich Hertz, an early pioneer in electronics.

He was the first scientist to prove the existence of E-M waves.

Many other E-M units of measurement are named after the scientist who discovered them.

For example, 30 MHz (10M band) means the wave goes up and down 30 Million times per second.

 

FREQUENCY=0

DIRECT CURRENT

A frequency of 0 is Direct Current (DC).

Think about the lead acid battery in your car.

It is very old technology from the 1800s

and we are still using it because it can put out high current.

It has 6 series connected cells, 2 Volts each, 2X6=12 Volts.

The electro-chemical reaction inside the battery

acts like an electron pump when you use current from that battery,

such as lights.

The starter motor draws around a hundred Amps which is a lot of current.

That's why the wires from battery to starter are big and thick.

 

BATTERIES

A battery has 2 or more cells connected in series or parallel.

Fully charged or dead,  any battery still contains the same number of electrons.

Batteries don't create electrons, they just make them move.

The electrons are on a one way street (wires).

Ancient cars used generators to charge the battery and power lights, fans, etc.

 

ALTERNATING CURRENT

Then, we have Alternating Current (AC).

Current that goes both ways.

The alternator in your car makes AC which goes to a rectifier that 

changes AC to DC to charge the battery and provide power for lights,

stereo system, fans and other car things that use power.

Very ancient cars, from a century ago used generators that produced DC.

Alternators are more efficient and reliable.

 

Power plants use massive alternators to produce high voltage 60 Hz AC

that winds up in the outlets of your home or office.

Many other countries use 50 Hz AC.

 

ELECTRIC CARS

If you own an electric car, while driving, you are sitting on top of a big battery.

Batteries are DC and by themselves harmless, because they emit no radiation.

However the real danger is battery fires.

 

It's what happens to the DC from the battery that's concerning.

The motors driving the wheels use AC, so the DC from the battery pack

gets converted to AC by an inverter (opposite of a rectifier) to power the motors.

AC motors can be more efficient than their DC cousins.

The AC is not 60 Hz, which is basically harmless.

It is high frequency broadband AC and you are exposed to it.

The car generates a lot of RF noise, making radio reception noisy.

 

PARTICLE VS WAVE

The Particle Wave Duality:

E-M radiation (EMR) is both photons and waves! Not very intuitive, but very real.

Photons are massless, chargeless fundamental particles that can carry big E-M energy,

such as X/Gamma photons. Each photon is a quanta of energy.

 

QUANTUM

Quantum is the physics of the very smallest things we've found in nature.

It's become a popular term and subject with several theories behind it.

Typical for Physics these days. We're still trying to figure out how gravity

fits into the Quantum theories.

 

The definition of Quantum is "a discrete quantity of energy, 

proportional in magnitude to the frequency of the radiation it represents."

The higher the frequency, the higher the energy per photon and shorter the wavelength.

 

WAVES

E-M waves are even more interesting, as they have both electric and magnetic parts,

two Sine waves 90 degrees apart, one vertical, the other horizontal.

It may seem that Electric and Magnetic fields are separate forces.

Physics regards them as one force.

You can't have one without the other.

Electrons scooting down a wire create a magnetic field around that wire.

Moving magnetic fields induce electron movement in any wire affected by the field.

Amplitude (intensity, luminosity, magnitude) is proportional to energy per photon. 

 

The duality can be easily proven with simple equipment found in high school Physics labs.

The visible light part of the spectrum is about half and half particle and wave.

Lower frequencies are wave dominated, so we call it radio waves.

The particle component photon is hiding in there,

barely detectable using high tech lab gear.

 

PARTICLES

At the other end of the spectrum are UV, X-Rays and Gamma rays,

high energy photons that act like microscopic bullets.

Easily detectable using inexpensive instruments, such as geiger counters.

The E-M Wave component is barely detectable, but it is there,

only detectable using expensive lab equipment.

 

IONIZING RADIATION

When these photons go through your body, they leave a nasty path of destruction in their wake.

These high energy photons strip electrons from atoms and molecules, hence the term Ionizing radiation.

When they hit the DNA in the nucleus of cells,

they cause mutations that can lead to cancer and other awful health issues.

 

Contrary to popular belief, frequencies lower than visible light, for example, cell phone, wi-fi, 5/6 G data, radio stations,

microwave ovens are not ionizing. That doesn't mean exposure to those frequencies is always safe.

Some are safer than others.

 

On the surface of our planet, living things (us and everything else) are always exposed to radiation including the Gamma.

Some is from the Earth, some from the Sun, some from our technology and some from way out there in deep space.

It's quite a mixture and varies a lot depending on where you are.

Regardless of the radiation type, DISTANCE is your best friend.

CHERNOBYL DISASTER

Our bodies are equipped to deal with low levels of X-Rays and Gamma Rays.

Some scientists believe this is beneficial.

Exposure to high levels do the damage way too quickly, overwhelming and killing the person.

For example, many brave men did what had to be done at the Chernobyl nuclear disaster.

Unfortunately, most didn't live very long.

In response to Chernobyl,  Bio Superfood was developed by Dr. Michael Kuriak and crew to

help those few who survived to live longer and today,

it's become a trusted and effective supplement.
