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

What travels at 300 000 km per second?

That is the speed of light.That is the speed of light.That is the speed of light.That is the speed of light.

Why is the speed of light limited in a vacuum?

The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.

Why speed of light is greater than speed of sound?

The speed of light is the speed at which electromagnetic waves propagate through a medium. The speed of sound is the speed at which acoustic waves propagate through a medium. As the speed of sound relies on the medium moreso than the speed of light, sound propagates much slower than light.

Ratio of the speed of light in a vacuum to the speed of light in a material?

The index of refraction.
