Because the speed of light is determined by the electrical characteristics

of the medium, and the electrical characteristics of vacuum don't change.

Is the speed of light slower in air or in a vacuum?

Speed of light is max. in vaccum and slower in air.


Formula for refractive index in terms of speed of light in vacuum and speed of light in a medium?

Refractive Index= Speed of Light in Vaccum / Speed of Light in the material


Why use constants?

Constant is the speed of light and as the speed of light cannot change it is 'constant'


Is the speed of light in water should be more than the speed of light in a vacuum?

No. Light slows down whenever it passes through water. Nothing is faster than the speed of light in a vaccum.


What does special relativity say about the speed of light?

The speed of light is constant.


Is refractive index of air less than vacuum?

No, refractive index(RI) of air is more than that of vaccum. Infact RI of any medium is more than vaccum. RI of vaccum is 1. RI of any medium = c/v where c is speed of light in vaccum v is speed if light in medium whose RI with respect to vaccum is found. It is known that speed of light is maximum in vaccum so v < c, and RI > 1.


Can light exceed its normal speed?

No, according to current scientific understanding, light travels at a constant speed in a vacuum, known as the speed of light, which is approximately 299,792 kilometers per second. This speed is a fundamental constant of nature and cannot be exceeded by light or any other object.


What is speed that does not change - called?

constant


Why is the speed of light constant?

The speed of light is constant because it is a fundamental property of the universe, as described by the theory of relativity. This constant speed of light plays a crucial role in maintaining the consistency of physical laws and the structure of spacetime.


Is speed of light constant?

yes


Is the speed of light a constant?

Yes


Does light accelerate?

Light does not accelerate in the traditional sense, as it always travels at a constant speed of approximately 299,792 kilometers per second in a vacuum. This speed is a fundamental constant in physics known as the speed of light.
