Discussion Overview

The discussion revolves around the effects of two counterphase waves emitted from the same source on a conductive material. Participants explore the implications of wave interference, electron displacement, and the nature of wave production from a single source versus multiple sources.

Discussion Character

  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that two waves in counterphase from the same source do not produce electron displacement in a conductive material.
  • Another participant questions the feasibility of two distinct waves being produced by the same source, seeking clarification on the terminology used.
  • A participant argues that if two waves are perfectly in line and emitted from the same source, they cannot be considered distinct waves, leading to confusion about the original question.
  • There is a discussion about the implications of feeding two amplifiers into a single antenna, suggesting that this would result in no voltage being produced, thus not generating a wave.
  • Another participant elaborates on the scenario of using two synchronized transmitters in antiphase, indicating that this would lead to power dissipation in the transmitters rather than effective wave production.
  • Concerns are raised about the coupling effects when using two antennas in close proximity, which could complicate the expected outcomes of wave interference.

Areas of Agreement / Disagreement

Participants express disagreement regarding the nature of wave production and the implications of counterphase interference. No consensus is reached on the effects of these waves on conductive materials or the definitions of wave sources.

Contextual Notes

Participants have not clarified the assumptions regarding the definitions of "waves" and "sources," nor have they resolved the mathematical implications of the scenarios discussed.

i am writing this message after a short consultation with kuruman. if there are two waves emitted by the same source then with the same direction, but these waves are in counterphase link: https://www.google.com/imgres?imgurl=https://lookaside.fbsbx.com/lookaside/crawler/media/?media_id=100325080043803&imgrefurl=https://www.facebook.com/counterphase/about/&docid=OpDdx0c440xCIM&tbnid=ol8qNK1IvHWYVM&vet=1&source=sh/x/im. when these two waves affect a conductive material they do not produce any electron displacement ?? This is new link https://www.google.com/imgres?imgur...eLM&tbnid=HntqSYCn1_AiZM&vet=1&source=sh/x/im

Hmm, what does this mean? How can two distinct waves be produced by the same source?

hi Dale I wrote "emitted from the same source" to show that they are perfectly in line. however, if two linear waves on the same plane, which have the same amplitude and frequency but in phase opposition, when they affect the incident material, do not produce any electron displacement?
 
That doesn’t answer my confusion about your question. The only way to be perfectly in line everywhere is to be emitted from the same source, so you are just saying the same thing again. If they are from the same source (so they are perfectly in line everywhere) then how can they be considered two distinct waves?

My confusion about your question is that you are describing one wave but calling it two waves. If you have a single antenna and you are feeding it with two amplifiers that are equal and opposite then you are not producing any voltage in the antenna. You don’t have a wave at all. You are just feeding power directly from one amplifier into the other (which will damage the amplifiers). If you have two separate antennas then they are not the same source / they are not perfectly in line everywhere.

@lambjx You are describing a source that emits nothing, but in a more "complex" way.

If you used two transmitters (synchronised RF feeds in antiphase ) and fed them to the same point on an antenna, then there would be Zero Volts at that feed point. (In the thought experiment, the two feed lines would be the same length, of course). What would happen to all the Power from the transmitters? All that power would be dissipated within the transmitters - they would just get much hotter than when operated correctly - say with 50% efficiency.
If two different antennae were used, they would have some small separation and there would be some power directed in most direction and zero power in the direction where cancellation occurs. Having the antenna very close together would involve strong 'coupling' between the two transmitters so they would 'see each other'. You would get similar problems to what you get when sharing one antenna.
