How do we measure light speed ????
Answers
Answer:
Explanation:
When the Earth is farther away, it takes light from Io longer to get to Earth resulting in a longer apparent orbital period of Io. So, just measuring the change in apparent period and the change in distance gives an estimate for the speed of light. This is exactly how Roemer estimated the speed of light.
