Tell us about yourself I am a: Another French physicist, Leon Foucault, used a rotating mirror rather than a wheel. The exsit of medium will then reduce the travel of light, the water reduce stronger than air. Download Project. Please note: Submit Form. Share this science project.
The speed of light in a vacuum is 186,282 miles per second 299,792 kilometers per second , and in theory nothing can travel faster than light. Similarly, even though Earth is orbiting the sun, which is itself moving around the Milky Way, which is a galaxy traveling through space, the measured speed of light coming from our sun would be the same whether one stood inside or outside of the galaxy to calculate it.

Sunlight takes about 8 minutes to reach our eyes, so the sun is about 8 light-minutes away. He concluded that light took 10 to 11 minutes to travel from the sun to Earth, an overestimate since it in fact takes eight minutes and 19 seconds.

He went on to explain that, while special relativity provides an absolute speed limit, general relativity allows for broader distances. A Refraction Experiment.

The velocity of light changes depends on the material it travels through. The eclipses lagged the most when Jupiter and Earth were farthest apart, and were on schedule as they were closer.
That doesn't stop sci-fi writers, and even some very serious scientists, from imagining alternative theories that would allow for some awfully fast trips around the universe.
In 1905, Albert Einstein wrote his first paper on special relativity. The third type of light behavior is refraction.
