"What, Mr. Huygens' calculation of the light speed is incorrect?"
Hearing Xu Yun's words,
Faraday was stunned.
It is well known.
The unit of light speed is very large, so the presence of an error is quite normal, even inevitable.
Not mentioning anything else.
Just compare the results calculated by Huygens and Little Niu.
One is 212,000 kilometers per second, and the other is 210,000 kilometers per second, a difference of 2,000 kilometers.
But the error Xu Yun spoke of that needed correction was obviously not just a minor numerical discrepancy.
The error he referred to was undoubtedly at the 'magnitude' level, at least over 20%.
But...
How is this possible?
To know.
Unlike the exploration of the essence of light.
Because the speed of light is so fast that in everyday life, people cannot perceive that it takes time for light to travel from point A to point B.
