- The Sun is 1.519×108 km from the Earth. How long in minutes does it take for light from the Sun to reach the Earth? c=3×108 m/sarrow_forwardIn the 1670s, Ole Rømer observed eclipses of the Galilean satellite Io as it is plunged through Jupiter’s shadow once per orbit. He noticed that the time between observed eclipses became shorter as Jupiter came closer to the Earth and longer as Jupiter moved away. Rømer calculated that the eclipses were observed 17 minutes earlier when Jupiter was in opposition compared to when it was close to conjunction. This was attributed by Rømer to the finite speed of light. From Rømer’s data, compute the speed of light, first inAU min−1, and then inm s−1.arrow_forwardWhat is the value for the constant for the speed of light?arrow_forward
