Phase and anti phase
« on: April 22, 2009, 13:27:20 pm »
Food for thought:

Two oscillators that have the same frequency and different phases have a phase difference, and the oscillators are said to be out of phase with each other. The amount by which such oscillators are out of step with each other can be expressed in degrees from 0° to 360°, or in radians from 0 to 2?. If the phase difference is 180 degrees (? radians), then the two oscillators are said to be in antiphase. If two interacting waves meet at a point where they are in antiphase, then destructive interference will occur. It is common for waves of electromagnetic (light, RF), acoustic (sound) or other energy to become superposed in their transmission medium. When that happens, the phase difference determines whether they reinforce or weaken each other. Complete cancellation is possible for waves with equal amplitudes.

more:

In physics, interference is the addition (superposition) of two or more waves that result in a new wave pattern.

Interresting , there was a youtube video by some optical-electro engineer talking about this , youtube removed the user like 1 hour aftrwards .

Couldnt find anything , I tried all the key-words I tried , the video was gone  ... It was some conference with some engineer guy , he simply explained what the dam scalar finally were . I always do a search on youtube for "scalar waves" and such .

A lady asked about scalar waves , he simply drew some mirror waveform kinda like Meyers and said that scalar waves happens when 2 waves , w/e waves , of same frequency w/e frequency , cancel out eachother . This creates what he called "interference patterns" ... Again , this is all textbook and nothing special .

But it was nice to finally get a definitive answer .

Hi,

Well, Stan said that his hydrogen generator worked on a system that was 180 degrees out of phase.
Sofar i can follow Dankie. The question is what was 180 out of phase?
If you hit voltage against voltage, you get zero.
Same frequency against same frequency = noice
In a RC setup you can shift voltage against amps.
What would it bring if you cut of the signal before amp kick in and after voltage raised?

Again, i just wrote some food for thoughts

Yes Stevie , It would be interresting to see with a phase meter the relation of currents of both negative side and positive side  of the cell .

well in a series resonant circuit the current is always the same.
if we have  +-----L-------C------- the voltage at the coil will be 90° before current, and the voltage on the capacitor will be 90° behind the current, which makes 180° degrees voltage difference between the two parts.
if you measure the whole voltage over L and C and the current you will notice both will be in phase at resonance.

"180 degrees out of phase with the electrolysis process"

Electrolysis:
High amps
Low volts
Chemicals
Electrons in
Chemical Process
Inefficient

Stan:
Low amps
High volts
No Chemicals
Electrons out
Physical Process
Efficient

Everywhere electrolysis is up, Stan is down, when electrolysis is one thing, Stan's is the other. It is the complete opposite. 180 degrees out of phase.
