Question

PLEASE HELP IMMEDIATELY

1. Based on the context, what does "Jovian" refer to?
2. Before Roemer calculated the speed of light, how fast was the speed of light thought to be?
3. What was the problem with Galileo's experiment to measure the speed of light?
4. Roemer's calculations were not completely correct. Did he calculate too high or too low for the speed of light?

Answer 1

I don’t know the answer for the first question but the answer for the second question is 301000km/s by James Bradley.

And for the third one, Galilio’s problem was that light was very fast to be measured by using his way.

And for the last one I think it was to low
