In fact, the light path of the rotating mirror method for measuring light speed can be shortened to around 20 meters, but Xu Yun opted for five kilometers, a value that the University of Cambridge could spare, to enhance the experiment's appeal.
Conducting an experiment in a 20-meter space and demonstrating it over five kilometers would attract audiences on completely different levels.
Anyway, the light path and the rotational speed of the mirror have a positive correlation; when the light path is extended, you just need to adjust the speed accordingly.
As Xu Yun approached the edge of the site.
Faraday stood silently alongside Stokes at the control panel, frowning, saying nothing.
Their expressions held unmistakable confusion but also glimpses of understanding, as if they were touching some boundaries.
Seeing this, Xu Yun stepped forward and greeted the eminent figures one by one:
"Your Majesty Albert, Dean Huai Wei, Mr. Faraday, Professor Stock, good evening."
"Hm?"
