All of the mechanical waves below need a medium (solid, liquid, gas) to travel through


Waves that oscillate up and down as they travel distance. Examples of these waves are earthquakes underneath the surface. They oscillate at different frequencies and have a measured wavelength from crest to crest. They transfer energy


These waves transfer energy through particles laterally. They have high pressure points and low pressure points. From high pressure to high pressure measures their wave length. Sound works this way by transferring vibrations through air molecules


These waves travel through a medium such as water or the earth. Seismic waves are surface waves. They consist of many particles oscillating up and down again to create a wave.
