How does knowing how fast light travels help scientists measure distance quizlet
Describe Olaus Roemer's experiment. Olaus Roemer was the first to try to measure the speed of light in 1675. He did this by measuring the periods of Jupiter's moons. Olaus found that when earth was rotating opposite the moon, Jupiter's moons' period appeared longer than when we were facing the moon.nother experiment measuring the speed of light was performed by Albert Michelson in 1880. He reflected light on an octagonal block with mirrors on each side (eight sides). The light was reflected from one of the mirrors to a mirror on a hillside a distance away.
