The aboriginal acknowledged altitude of the acceleration of ablaze took abode in 1676. Danish astronomer Ole Rømer was aggravating to admeasurement the apogee of Io, Jupiter's third better moon, by watching how continued it took to canyon about the planet. Watching Io over abounding years, Rømer fabricated a hasty discovery, says the American Museum of Natural History:

Refraction | speed of light in m sThe time breach amid alternating eclipses became steadily beneath as the Earth in its apogee confused against Jupiter and became steadily best as the Earth confused abroad from Jupiter. These differences accumulated. From his data, Roemer estimated that back the Earth was abutting to Jupiter..., eclipses of Io would action about eleven account beforehand than predicted based on the boilerplate alternate aeon over abounding years. And 6.5 months later, back the Earth was extreme from Jupiter..., the eclipses would action about eleven account after than predicted.
Roemer knew that the accurate alternate aeon of Io could accept annihilation to do with the about positions of the Earth and Jupiter. In a ablaze insight, he accomplished that the time aberration charge be due to the bound acceleration of light.

Light | speed of light in m sBefore Rømer, scientists were borderline if light had a bound speed or if its speedometer was assuredly ashore at “infinite.”
A few hundred years later, techniques for barometer the acceleration of ablaze accept developed astoundingly added precise and, in some cases, added complex. But in the video above, the association at the At Bristol science center show off a almost simple way to account the acceleration of ablaze that doesn't absorb years of attractive through a telescope eyepiece. In fact, their access uses annihilation but simple kitchen equipment—and chocolate.

The video doesn't accomplish it altogether bright how barometer the broiled $.25 on a amber bar relates to the acceleration of light. But breaking it bottomward a little added aloof requires demography a attending at some of the units acclimated in their measurements.
Hertz is the physics amateur for “cycles per second.” The microwave used in the video produced ablaze after-effects with a abundance of 2,450,000,000 Hertz, or that abounding cycles per second. Going from aiguille to aiguille in a wave—in this case the ambit amid the aboriginal and third broiled bit of chocolate—is one cycle. Exton and Shah abstinent that ambit as 0.12 meters, or 0.12 meters per cycle. Multiplying commodity abstinent in “meters per cycle” by commodity in “cycles per second” will accord a altitude in “meters per second.” That's the wave's velocity—the acceleration of light.

Refraction. - ppt video online download | speed of light in m sThe ambush that makes the At Bristol team's access assignment is that we in the avant-garde era already apperceive a few important things about light: that it has a bound speed, and that that acceleration is abundantly constant. We additionally accept the account of physicists accepting already teased out the accord amid beachcomber length, abundance and velocity.
When Ole Rømer looked to Jupiter and aboriginal deduced the acceleration of ablaze he came up with 214,000,000 meters per second. “This measurement, because its antiquity, adjustment of measurement, and 17th aeon ambiguity in absolutely how far Jupiter was from the Earth, is decidedly abutting to the avant-garde amount of [299 792 458] meters per second,” says Dave Kornreich for Cornell.
