I think the term is "medium"
ie, "As the wave travels from one medium to the next..."
The name is "electromagnetic waves". They can travel through empty space, and - depending on the specific frequency - through certain materials. For example, light can travel through glass.
The material through which waves travel is called a medium. This could be a solid, liquid, or gas.
Elastic waves, particularly sound waves and seismic waves, can travel through the Earth's atmosphere. Sound waves propagate through the air, while seismic waves are generated by earthquakes and travel through the Earth's crust and mantle.
Electromagnetic waves, such as light and radio waves, can travel through a vacuum because they do not require a medium for propagation.
Surface waves (as the name suggests) travel along Earth's surface. Seismic waves that travel through earth's interior are known instead as body waves.
They are called sound waves. Their name does not change just because they travel in water.
(1) Electromagnetic waves, (2) gravitational waves.
The waves of energy that an earthquake produces are called seismic waves. There are two main types: body waves, which travel through the Earth's interior, and surface waves, which travel along the Earth's surface.
Sound cannot travel through vacuums. It needs a medium for its waves to process, meaning the molecules need to vibrate in order for sound to be heard. Space is a good example of a vacuum that sound cannot travel through. In the movie Alien, they tag line : "In space, no one can hear you scream," and that is true.
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
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.
