Discussion Overview

The discussion revolves around the effects of pulsing a frequency, specifically 60 Hz, on the distance that the wave can travel through a medium. Participants explore whether pulsing the frequency at a rate of 10 times a second would increase the penetration distance of the wave into an object.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether pulsing the frequency would amplify the distance the wave travels, suggesting that it would not unless pulsing increases the amplitude.
  • Another participant emphasizes the need for a clearer definition of the problem, noting that the waveform of the pulses could introduce harmonic components that might affect propagation.
  • Concerns are raised about the penetration of the 60 Hz frequency into different materials, with a distinction made between non-metallic and metallic objects regarding induced currents.
  • A request for clarification on the participant's goals is made, indicating a desire to better understand the context of the question.

Areas of Agreement / Disagreement

Participants express differing views on the effects of pulsing on wave propagation and penetration, indicating that the discussion remains unresolved with multiple competing perspectives.

Contextual Notes

There is a lack of clarity regarding the specific definitions of terms like "penetrates into an object" and the characteristics of the pulsed waveform, which may affect the discussion's conclusions.

Explanation: Let's say I have something generating a frequency of 60hz. If I pulse that frequency on and off, 10 times a second, does that amplify the distance that wave will travel through space? Let's assume the medium it is traveling through is consistent for the moment. If the 60hz penetrates into an object, say 10 inches, would pulsing the frequency 10 times a second, or faster the number is just an example, would that increase the penetration distance? Thanks in advance for answering a somewhat odd question.

No, not unless for some reason making the emission intermittent allows you to increase the amplitude.

I assume we'tre talking about EM radiation...

You haven't really defined the problem well enough for a definitive answer.
It would have to depend on the waveform of the 10Hz 'pulses', If they are good, fast square waves then you could have harmonic components well up into the kHz range and depending on what supply leads were involved, some EM Power could well be radiated by the connecting wires.
You would need to specify what you actually mean by "penetrates into an object". The 60Hz alternating magnetic field around the wires would propagate through non metallic objects but would induce largely surface currents into a metallic object.
