In the compression part of a wave, the medium is more dense as the particles are packed closely together. In the rarefied area, the medium is less dense and the particles are further apart.

Yes. Electromagnetic waves, like light, can travel through a vacuum, they need no medium in order to be transmitted. Unlike sound waves, which are compression waves what rely on matter in order to be transmitted.
The medium-sized rock sample had approximately 30% empty space, meaning 30% of its volume was not occupied by solid material.
Sound requires a medium, such as air or water, to travel through. In the absence of a medium, such as in empty space, there are no particles for sound waves to propagate through, so sound cannot travel.
Sound waves do not travel through empty space because they require a medium, such as air, water, or a solid, to propagate. Similarly, mechanical waves like seismic waves also need a medium to travel and cannot propagate through empty space.

If they were they would not travel through a vacuum because there would be nothing to compress. But they do travel through vacuums, so they can't be compression waves. More detail... The above does not exclude a medium that can exist in a vacuum For EM waves to be a compression wave, it must have some medium. For many years, the ether/aether was considered to be the medium, but the Michelson-Morley experiment failed to show any effect consistent with ether/aether, and the concept is now considered invalied. So, since the ether/aether cannot be detected, EM waves have no medium, so EM waves are not compression waves.

In a way, they don't. There is always a medium; though for some waves, this medium can be empty space.
