Light travels fastest in a vacuum.
When light passes through a medium, such as air or water, it can be absorbed, scattered, or refracted, which can change its speed and direction. In a vacuum, light travels at its maximum speed and does not interact with any medium, so it does not experience these changes in behavior.
The properties of a vacuum medium include having no particles or matter present, and being transparent to light. This lack of particles allows light to travel through a vacuum at its maximum speed, which is the speed of light in a vacuum. This means that light can travel long distances without being absorbed or scattered, making vacuum an ideal medium for the transmission of light.
The speed of light in a medium is determined by its parameters mu and epsilon, which represent the medium's ability to conduct and store electric and magnetic fields. This speed is slower than the speed of light in a vacuum because the medium affects the propagation of light waves.
"Fast light" refers to light moving at its maximum speed in a vacuum, which is approximately 299,792 kilometers per second. "Fast sound" refers to sound waves traveling at their maximum speed in a medium, which is approximately 343 meters per second in air at room temperature.
The speed of light of different colors passing through the same medium remains the same. This is because the speed of light in a medium is constant and does not change based on the color of the light.
The speed of light is not medium: in vacuum, it is the highest speed that there can be. Hardly a definition of medium!

No, light in a medium will travel at a slower speed.
c divided by the index of refraction of the medium = the speed of light in the medium.
That quotient is the refractive index of that medium.
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
No, the speed of light is not the same in all optical media. It changes depending on the medium through which light is traveling, such as air, water, or glass. The speed of light is slower in denser media compared to a vacuum, where it travels at its maximum speed.
It's the speed of light in vacuum divided by the speed of light in that medium.
No, not as long as the light stays in vacuum.No, it does not. That is where it has its maximum speed.

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.
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.
