Waves are described by:
their length (wavelength)
their height or depth (amplitude)
the number of waves you can count in a given amount of time (frequency)
A wave is simply a way by which energy can be moved through a material without actually moving the material itself. they travel through light, air, water, and sound.
There are three basic kinds of waves:
compression waves
transverse waves
surface waves

Because they are waves, and waves travel that way.
The only waves that are known and proven to travel through empty space are electromagnetic waves. Theoretical gravitational waves also travel through empty space but have not yet been proven to exist. Both electromagnetic and gravitational waves move at the speed of light, thus it could be argued that a general term to describe all waves that can travel through empty space are waves that move at the speed of light.They say the message is the medium. In this case you could call it the "Ether". Ether is a blanket term describing information that is transmitted by any source through any medium. In this case the emptiness of space.
sound wave need material becuse sound wave formed by compresion and rarefaction
sound waves bounce off of walls. they need air to travel.
electromagnetic waves can travel through vacuum while water waves travel in water.
I am not sure that there are many scientists who describe time travel. those that describe light waves are physicists.
Sound waves are caused by vibrations and travel as longitudinal waves which cause by the vibration of the molecules in air (the molecules dont actually move)
Because they are waves, and waves travel that way.
How are radio waves formed?
Body waves Body waves and surface waves are the two types of seismic waves formed during great earthquakes. P waves and S waves are called body waves because they travel through the body of the Earth. Surface waves Love waves and Rayleigh waves travel only on the surface of the Earth and cause the most destruction.

no p waves travel faster than s waves
A surf is formed when the waves get to high and cause waves to "break."
sound wave need material becuse sound wave formed by compresion and rarefaction
Potential energy is transformed into seismic waves during an earthquake :)
sound waves bounce off of walls. they need air to travel.
electromagnetic waves can travel through vacuum while water waves travel in water.
