One way speed of light measurement

Click For Summary
SUMMARY

The discussion centers on the impossibility of measuring the one-way speed of light using a round-trip measurement method involving a timer and mirrors. Participants assert that any measurement of light's speed is inherently tied to the synchronization convention used, making it impossible to derive the one-way speed independently. The conversation emphasizes that while round-trip measurements can confirm the speed of light as a defined constant (approximately 3×108 m/s), they cannot provide insights into the one-way speed due to the dependence on synchronization. Key references include Reichenbach’s synchronization convention and its implications for measuring light speed.

PREREQUISITES
  • Understanding of the speed of light as a defined constant (c)
  • Familiarity with synchronization conventions in physics, specifically Reichenbach’s synchronization convention
  • Basic knowledge of round-trip versus one-way measurements
  • Awareness of the implications of experimental design in physics
NEXT STEPS
  • Research Reichenbach’s synchronization convention and its historical context
  • Explore the differences between round-trip and one-way measurements in physics
  • Study the implications of synchronization on the measurement of light speed
  • Examine existing experiments and discussions surrounding the measurement of the speed of light
USEFUL FOR

Physicists, students of physics, and anyone interested in the fundamental principles of light speed measurement and synchronization conventions.

Maybe you should start there then. Your calculation does not show anything about what information can be gained about Reichenbach’s ##\epsilon## with your approach. Therefore, it sheds no information whatsoever on the one way speed of light.

Calculations need to be posted directly in the thread using the PF LaTeX feature (you will see a "LaTeX Guide" link at the lower left of the post window if you need help with that), not in an attachment.
