Observations of Jupiter's moons provided the first real evidence that light had a speed and wasn't instantaneous. Essentially, the orbit of Jupiter's moons was known fairly accurately over the short term, but over longer time periods (a few months) the moons appeared to lag behind or speed ahead of their predicted positions. Eventually it was realized that this was because the Earth-Jupiter distance changes as they orbit the Sun, and the difference was due to the extra time the light required to reach us when the distance was further.
What else can I help you with?
Is sound the fastest speed possible?
No!...Speed of light is the fastest speed possible, but now a new particle called lepton is more faster than light...rather it is has the fastest speed discovered till now.It travels in the same wave as light travels i.e tranverse waves.
Who discovered that the electric current flows at the speed of light?
The discovery that electric current flows at the speed of light is attributed to a Scottish physicist named James Clerk Maxwell. In his equations known as Maxwell's equations, he determined that the speed of electromagnetic waves, which includes light and electricity, is constant and equal to the speed of light.
Is it light speed or the speed of light?
speed of light I think well it sounds right:)
Who discovered lightspeed?
The theory that nothing can travel faster than the speed of light in a vacuum was first proposed by the famous physicist Albert Einstein in his Theory of Relativity in 1905. The concept of the speed of light being constant and a universal speed limit has since been confirmed through various experiments and observations.
Is it possible to travel at the speed of light in water?
No, it is not possible to travel at the speed of light in water. Light travels at a slower speed in water compared to its speed in a vacuum, which is about 299,792 kilometers per second. The speed of light in water is approximately 225,000 kilometers per second.
What is Michelson famous for?
he discovered the speed of light
Why is light speed the ultimate?
This is because nothing else in the entire discovered universe moves as fast as the speed of light!
Who discovered the equation energy times speed of light squared?
Einstein
What did Olaus Roemer invent?
Olaus Roemer discovered the speed light in 1676.
Who was the first to find the speed of light?
it was MAxwell the dude who discovered electromagnetic waves
What can be discovered if something is found which has greater speed than light?
probably all kinds of technology
Is sound the fastest speed possible?
No!...Speed of light is the fastest speed possible, but now a new particle called lepton is more faster than light...rather it is has the fastest speed discovered till now.It travels in the same wave as light travels i.e tranverse waves.
When was speed discovered?
The second species in any environment.It was either a predator and wanted to move faster than the first to catch and eat it, or it was the prey and wanted to get away! So several millions of years before the first humanoid.
When Michelson and Morley measured the speed of light in various directiion they discovered that?
... its speed is the same in any direction, even if you're movingin that direction or in the direction opposite to it.
Is it true albert invent speed of light?
No, the speed of light was not invented - it's a natural phenomenon. Albert Einstein discovered the equation E=mc2. This tells us that if an object was to randomly turn into energy, the amount of energy would be equal to the objects mass multiplied by the speed of light twice.
What did Olaus Roemer discover about light?
Olaus Roemer discovered the finite speed of light in the late 17th century. He observed that the time it took for light to travel from Jupiter to Earth varied as the distance between the two planets changed, leading him to calculate a rough estimate of the speed of light. This discovery laid the foundation for later, more precise measurements of the speed of light.
Who discovered that the electric current flows at the speed of light?
The discovery that electric current flows at the speed of light is attributed to a Scottish physicist named James Clerk Maxwell. In his equations known as Maxwell's equations, he determined that the speed of electromagnetic waves, which includes light and electricity, is constant and equal to the speed of light.
