Waves and Sound

The Nature of Waves
A wave is a rhythmic disurbance that transfers energy
-All waves are made by something that vibrates.

Mechanical waves need a matter medium to travel through.
(sound,water,seismic)

Two basic types of waves
a)Transverse
b)Compressional (longitudinal)

Amplitude- Size related to the energy carried by the wave (height)
