No, a vacuum is not considered a medium because it is the absence of matter, including air or any other substance.
Light can travel through vacuum, but it is not a medium.
Vacuum is not a medium. Considering waves, mechanical waves require a medium (such as air) to travel. Electromagnetic waves (such as visible light and radio waves) do not require a medium, and are the only waves (that we know of) that can travel through a vacuum. I have heard of a gravity wave, which may be a third type of wave. I don't know much about them. These would also travel through a vacuum.
Mechanical waves can't pass through a vacuum. Mechanical waves need something to pass through. Space is generally considered a vacuum, with nothing in it to transmit a mechanical wave.
An ocean wave is considered to be a mechanical wave, as it requires a medium (water) to propagate. Electromagnetic waves, on the other hand, do not require a medium and can travel through a vacuum.
Sound waves cannot travel through a vacuum because it needs a medium and a vacuum has nothing within it that can act as a medium.

The speed of light is not medium: in vacuum, it is the highest speed that there can be. Hardly a definition of medium!

Sound waves cannot travel through a vacuum because it needs a medium and a vacuum has nothing within it that can act as a medium.
Convection requires a medium, such as a gas or liquid, to transfer heat through the motion of the medium itself. In a vacuum, there is no medium to carry the heat, so convection cannot occur. Heat transfer in a vacuum primarily occurs through radiation.
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.
No, light in a medium will travel at a slower speed.
When light goes through any medium other than a vacuum, its speed is normally slower than in a vacuum.
The speed of sound cannot be measured in a vacuum because there is no medium for sound waves to travel through in a vacuum. Sound requires a medium such as air, water, or solids to propagate.
