Does light require a medium for transmission?
We know that light doesn’t need a medium through which to travel because the speed of light is experimentally constant: independent of the movement of the source or detector or the direction in which it travels. Light contrasts with sound, which travels through the air (or some other material medium).
Is empty space a medium?
The common explanation for this is that space is a vacuum and so there’s no medium for sound to travel through. Space is never completely empty – there are a few particles and sound waves floating around. In fact, sound waves in the space around the Earth are very important to our continued technological existence.

What type of waves require a medium?
Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum.
What type of medium is ocean waves?
Mechanical Waves Light, sound, and waves in the ocean are common examples of waves. Sound and water waves are mechanical waves; meaning, they require a medium to travel through.
What medium do sound waves travel through?
Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. Liquids are not packed as tightly.
What medium do sound waves travel the fastest?
solids
