Can the speed of light be calculated?
Answer: The speed of light was determined through experimentation, such as the timing of moons passing behind Jupiter. Many formulas are based upon the speed of light, but that number had to be determined beforehand. Light travels 299,792,458 meters per second (or 186,282.397 miles per second in a vacuum. Answer: Yes, the speed of light can be deduced from the electrical properties of empty space. However, in practice it is more accurate to measure the speed of light.
How can the index of refraction for different substances be determined mathematically?
n(index of refraction) = c(speed of light in a vacuum)/v(speed of material in the sebstance)
Is speed of light uniform or not?
The speed of light in a vacuum is constant everywhere. The speed of light in a particular medium depends on what the medium is. It moves slower in air than in a vacuum, and slower in water than in air.
What is universal speed limit?
The human speed limit has not yet been identified but one way to be sure is to calculate the energy muscle can provide for our legs. For example, in a 100m race, the amount of kinetic energy can be calculated. Usain Bolt's kinetic energy for the world record is about 369.56J. So, in order the know the max limit of human speed ,just get the max energy our body can provide at an instance.
Speed of light in a vacuum is determined by what?
The speed of light (and all other forms of electromagnetic radiation) in vacuum is determined bythe electrostatic permittivity (ε0) and magnetic permeability (μ0) of free space.An interesting thought ... we have no way of knowing whether these physical constants are the samenumbers today that they have always been. If either of them has changed since the birth of the universe,then the speed of light changed, and our observations of the earliest cosmos give an erroneous numberfor the age of the universe.But anyway, that's what these quantities are today, and they're what determines the speed of light,as is so neatly predicted by Maxwell's equations and verified spot-on by the best measurements.
Who determined the speed of sound in water?
it was faucault who first measured the speed of light in water ......
Why does the speed of light remains same in a black hole?
The speed of light(roughly 186,000 Miles per second) is a universal constant.
Is the color of light determied by the speed of the light waves?
the color of light is determined by the ____ of the light waves A. medium B.speed C.frequency D. amplitude
Does the gravitation field of the black hole pulled objects in faster than the speed of light?
the answer is no; the speed of light is the universal speed limit, nothing travels faster
What is the highest speed possible for an object to travel?
The universal speed limit for material objects is c : the speed of light in a vacuum.
Why speed of light is constant in vaccum?
Because the speed of light is determined by the electrical characteristics of the medium, and the electrical characteristics of vacuum don't change.

Does the color of the laser affect the velocity of the light wave projected by the laser?
No, velocity and color are independent. Color is determined by frequency, and speed is determined by what material the light is traveling through.
What is the speed of light through the liquid whose refractive index you have determined?
If the refractive index is k then the speed of light is c/k metres per second where c is the speed of light in vacuum (approx 299,792,458 m/s).
What’s the speed of light?
Light is a "universal speed limit" and, according to Einstein's theory of relativity, is the fastest speed in the universe: 300,000 kilometers per second (186,000 miles per second).
Who is the scientist use the light year to measure the speed of light?
It doesn't work that way. The light-year is not used to measure the speed of light. It works the other way round: First, the speed of light is determined through other methods, then the distance called a light-year is calculated based on that measurements.
Is the speed of light in a medium affected by the velocity of the light as it enters a new medium?
No. The speed of light is determined by the electrical characteristics of the medium it's in, regardless of what medium it came from or what medium it's headed for when it leaves this one.
