Discussion Overview

The discussion revolves around the relationship between the wavelength of electromagnetic (EM) signals and the speed of photons. Participants explore how different wavelengths, such as those of gamma rays and radio waves, affect the propagation of light and the characteristics of the waves themselves.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants assert that all photons, regardless of wavelength, travel at the speed of light, but express confusion about how this relates to their wavelength and the notion of zig-zag paths.
  • One participant claims that photons in gamma rays travel through shorter zig-zag waves, suggesting this affects their distance covered, while another counters that photons do not travel along such paths.
  • Another participant clarifies that the waves represent variations in electromagnetic field strength and direction, not the motion of photons.
  • Participants question what wave characteristic must change if EM signals propagate at the speed of light but have different wavelengths, with some suggesting that only the wavelength changes, while others propose that the frequency must also change.
  • One participant references the equation c = fλ to illustrate the relationship between speed, frequency, and wavelength.

Areas of Agreement / Disagreement

The discussion contains multiple competing views regarding the nature of photon travel and the implications of wavelength on their propagation. There is no consensus on the interpretation of how wavelength affects the speed or behavior of photons.

Contextual Notes

Participants express uncertainty about the implications of wavelength on photon travel, and there are unresolved questions about the definitions and relationships between speed, frequency, and wavelength.

I know that there are different wave lengths, light and photons travels through these waves. All of them travel at the speed of light. But note that Gamma rays, and radio waves both travel at the speed of light, but the waves of gamma rays are shorter. So both gamma rays and radio waves travel about 186,000 miles(300,000 kilometers) per second. But the photons in gamma rays have to travel through short zig-zag like waves, so they cover a long distance. While radio waves have to travel through longer zig-zag like waves, so the cover a shorter distance. I hope you understand by what I mean. So the way I'm thinking the photons are traveling faster than the speed of light, which is impossible. Please help me.

Photons do not travel along a wavy zig-zag path.

The waves do not represent paths of motion of the photons. They represent variations in the strength and direction of the electromagnetic fields that are associated with the photons.
 
If EM signals propagate at the speed of light, but different signals have different wavelengths, what wave characteristic must change?

Just the wavelength changes.

The frequency of the said wave.
