What does special relativity say about the speed of light?
The speed of light is constant.
If special relativity states that the speed of light is a constant how can refractive index be an indication of a change in the speed of light?
The relativity statement refers specifically to the speed of light in a vacuum.
How slow can light go?
In some special substances, it was possible to slow the speed of light to just a few meters per second - incredibly slow compared to the speed of light in a vacuum.In some special substances, it was possible to slow the speed of light to just a few meters per second - incredibly slow compared to the speed of light in a vacuum.In some special substances, it was possible to slow the speed of light to just a few meters per second - incredibly slow compared to the speed of light in a vacuum.In some special substances, it was possible to slow the speed of light to just a few meters per second - incredibly slow compared to the speed of light in a vacuum.
Is the speed of light faster in a liquid?
No. According to special theory of relativity, the speed of light in all inertial mediums remains the same as that in the vacuum.
What are massless particles traveling the speed of light?
Massless particles traveling at the speed of light include photons, the particles of light. They have no rest mass and always move at the speed of light in a vacuum according to the theory of special relativity.
The speed of light is special because?
As far as they know, nothing goes faster.
Where does a photon get its speed from?
Nowhere. A photon must travel at the speed of light so it starts with that speed when it is created. This is the origin of the theory of special relativity.
What is constant in special theory of relativity?
The speed of light is a constant in the special theory of relativity, as it is the same for all observers in inertial reference frames. This constant speed of light serves as a fundamental principle in shaping the structure of spacetime and the behavior of physical laws in the theory.
How did Albert Einstein determine the speed of light?
Albert Einstein did not determine the speed of light, rather that the speed of light was the maximum speed possible in the universe. The speed of light was discovered in the late 1600's by Danish astronomer Ole Roemer, using Jupiter and its moon Io. It was later used in Maxwell's equations of electromagnetism, and then later used by Albert Einstein in his theory of special relativity.
What is the speed of a radiowave?
In free space, radio waves travel at the speed of light. In a material, such as co-ax cable, the speed is much lower, perhaps as low as 0.6 of the speed of light. Special arrangements may lower its speed even further.
What whould happend if uneverse expand faster than speed of light?
the far away galaxies may be moving faster than the speed of light already. In general relativity theory, expansion of space is not limited to the speed of light as it is in special relativity
What is the speed of light per planet?
The speed of light is the same for every observer everywhere. That is a fundamental tenet of the theory of special relativity (and everything based on it, such as the general theory of relativity and quantum field theory). To date no violation of the consistency of the speed of light has been measured. By the way, this does not say the speed of light is the maximum speed, just that the speed of light is constant, so the possible discovery of faster-than-light neutrinos does not invalidate this.
