Did you know there are three types of waves:
Mechanical waves require a material medium to travel (air, water, ropes). These waves are divided into three different types.
*Transverse waves cause the medium to move perpendicular to the direction of the wave.
*Longitudinal waves cause the medium to move parallel to the direction of the wave.
*Surface waves are both transverse waves and longitudinal waves mixed in one medium.
Electromagnetic waves do not require a medium to travel (light, radio).
Matter waves are produced by electrons and particles.

What type of waves are you making today?
None. Then you better get busy.
