history of the speed of light and how its speed was determined
What is the history behind determining the speed of light? How did past scientists determine it'salue value This video covers Rømer, Bradley, Fizeau and Foucault and how they determined the speed of light. CORRECTION: As some have noted I have made an error in the discussion on Rømer. I acknowledge this , and here is my correction as well as animation: https://youtu.be/TAIlswch5d0 👍 Really like this video?
