Galileo attempted to record the time between lantern signals but was unsuccessful because the distance involved was too small and light simply moved too fast to be measured this way. Around 1676, Danish astronomer Ole Roemer became the first person to prove that light travels at a finite speed.

The person who first showed that light is an electromagnetic wave was. James Clerk Maxwell in the 1860s. The first person to prove that light did not travel at infinite speed was. Ole Rømer. Flash of light is transmitted through 2 parallel tubes of length 1 km, one evacuated, the other with water.
Around 1676, Danish astronomer Ole Roemer became the first person to prove that light travels at a finite speed. He studied Jupiter’s moons and noted that their eclipses took place sooner than predicted when Earth was nearer to Jupiter and happened later when Earth was farther away from Jupiter.
How did scientists first prove that light had a finite speed?
Ole Rxf8mer first demonstrated in 1676 that light travels at a finite speed (non-instantaneously) by studying the apparent motion of Jupiter’s moon Io.
Who first proved that the speed of light is constant?
No matter how you measure it, the speed of light is always the same. Einstein’s crucial breakthrough about the nature of light, made in 1905, can be summed up in a deceptively simple statement: The speed of light is constant.
Who showed that the speed of light is finite?
Ole Rxf8mer’s 1676 demonstration that light propagates at a finite speed must have been a revelation to the members of the French Royal Academy of Science. A young and brilliant Danish “postdoc” at the Paris Observatory, Rxf8mer had unexpectedly answered a long-standing fundamental question.
What did Galileo assume about the speed of light?
Galileo would try to record how long it took light to get to him from across the field on which the experiment was done. His only conclusion was that light-speed was too fast to be measured by that experiment.
How did Roemer establish that the speed of light is finite?
Around 1676, Danish astronomer Ole Roemer became the first person to prove that light travels at a finite speed. He studied Jupiter’s moons and noted that their eclipses took place sooner than predicted when Earth was nearer to Jupiter and happened later when Earth was farther away from Jupiter.
How was the speed of light determined?
In the California mountains he surveyed a 35-km pathway between two mountain peaks, determining the distance to an accuracy of less than 2.5 cm. He made use of a special eight-sided revolving mirror and obtained a value of 299,798 km/sec for the velocity of light.
How did Michelson calculate the speed of light?
Rxf8mer interpreted this as the difference in the times needed for the light to travel between Jupiter and Earth. He obtained a value of 214,000 km/s compared to the current value 299,792 km/s.
How did Foucault determine the speed of light?
Foucault was able to use the angle displaced by the mirror and its angular speed to calculate the time of flight for light. Using the time of flight and the distance between the rotating and fixed mirrors, Foucault calculated light’s speed to be 299,792,458 m/sec.

How did Einstein know the speed of light was constant?
It can be derived from Maxwell’s equations that the speed at which electromagnetic waves travel is: c = ( ϵ 0 μ 0) − 1 / 2 . Since light is an electromagnetic wave, that means that the speed of light is equal to the speed of the electromagnetic waves. ϵ 0 and μ 0 are properties of the vacuum and are constants, so c will also be a constant.
