Light can travel through vacuum, but it is not a medium.
No, light cannot be seen in a vacuum because light requires a medium to travel through in order to be visible. In a vacuum, there is no medium for the light to interact with, so it cannot be seen.
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 is a maximum in a vacuum. In other media, such as air or water, the speed of light is slower due to interactions with the medium's particles.
No. light waves required no medium for transmission.
The absolute refractive index of a medium is a measure of how much light is slowed down when passing through that medium compared to the speed of light in a vacuum. It is a ratio of the speed of light in a vacuum to the speed of light in the medium. The absolute refractive index is a fundamental property of the material and is used to calculate how light rays will bend when entering or exiting the medium.

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.
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".
When light goes through any medium other than a vacuum, its speed is normally slower than in a vacuum.
It's the speed of light in vacuum divided by the speed of light in that medium.

A vacuum.
The speed of light in any medium isspeed of light in vacuum/refractive index of that medium.
No. light waves required no medium for transmission.
