Visible Light (there are other types), X rays, TV and radio signals.These came under the broad heading of electromagnetic waves.
Electromagnetic waves, such as light and radio waves, can travel through a vacuum because they do not require a medium for propagation.
The material through which waves travel is called a medium. This could be a solid, liquid, or gas.
(1) Electromagnetic waves, (2) gravitational waves.
Electromagnetic waves do not require a medium to propagate. They can travel through a vacuum, such as the waves that make up light, radio waves, and X-rays.
Electromagnetic waves, such as light and radio waves, do not require a medium to propagate. They can travel through a vacuum, like outer space, because they are made up of oscillating electric and magnetic fields.

The very name "mechanical waves" indicate that these need badly a material medium such as air, water etc.
I think the term is "medium" ie, "As the wave travels from one medium to the next..."

The electromagnetic wave used to send signals in satellites is called radio waves. These waves have long wavelengths and are able to travel long distances through space without the need for a physical medium.
P-waves are type of elastic wave, also called seismic waves, that can travel through gases (such as sounds), elastic solids and liquids, including the Earth. P-waves can be produced by earthquakes and recorded by seismometers. The name P-wave stands for primary wave, as the P-wave is the fastest among the elastic waves, compared to the S-waves.(Sources Wikipedia). Hope that helps! :D
