What was the percent error of Rømer's estimate? SolutionĮxperimental value = 220,000 km/s = 2.2 x 10 8 m/sĪctual value = 299,800 km/s = 2. The current accepted value of the speed of light is almost 299,800 km/s. In 1676, he determined that this phenomenon was due to the fact that the speed of light was finite, and subsequently estimated its velocity to be approximately 220,000 km/s. If Earth was traveling toward Jupiter, the eclipes of Jupiter by, say, Io, would last for a shorter amount of time, while if Earth was traveling away from Jupiter, the eclipses would appear to be longer. The 17th century Danish astronomer, Ole Rømer, observed that the length of the eclipses of Jupiter by its satellites would appear to fluctuate depending on the direction Earth was traveling relative to Jupiter at the time of the eclipse. It is always necessary to understand the cause of the error, such as whether it is due to the imprecision of your equipment, your own estimations, or a mistake in your experiment. A percentage very close to zero means you are very close to your targeted value, which is good. The experimental value is your calculated value, and the actual value is the known value (sometimes called the accepted or theoretical value).
