Sound waves and gamma rays.
p waves
Sound travels through matter as transverse pressure waves.
Mechanical waves need some kind of material to transmit through. They involve the shaking and passing of energy through matter. Electromagnetic waves don't need a medium to travel through. Outer space is considered a vaccuum, there is no matter to shake back and forth to create a wave. This is why electromagnetic waves can travel through solids, liquids, and why they travel faster.
S-waves can not travel through liquids. By Hollie

Electromagnetic waves don't need anything to travel. This kind of waves does not need a medium to move through, therefore they can even travel through outer space.
