Comment on 'A one-way speed of light experiment'
Rodrigo de Abreu, Vasco Guerra
TL;DR
This paper critiques a recent experiment claiming to measure the one-way speed of light, clarifying that it actually measures the two-way speed, highlighting common misconceptions in such measurements.
Contribution
It clarifies the distinction between one-way and two-way light speed measurements and corrects a common experimental misconception.
Findings
The experiment measures the two-way speed of light, not the one-way speed.
Misinterpretations can lead to incorrect conclusions about light's speed.
Clarifies the importance of experimental design in speed of light measurements.
Abstract
A recent paper published in Am. J. Phys. describes an experiment designed to measure the one-way speed of light. Although the experiment is very interesting, in particular to be used in student laboratories, it is in fact determining the two-way speed of light.
