Mechanical waves
Mechanical waves
Energy moves through material without transporting the material
Medium (in wave context)
Medium (in wave context)
Material through which mechanical waves pass
Transverse waves - particle motion direction
Transverse waves - particle motion direction
Perpendicular (at right angles) to wave direction
Longitudinal waves - particle motion direction
Longitudinal waves - particle motion direction
Parallel to the direction the wave travels
Example of longitudinal wave
Example of longitudinal wave
Sound waves
Speed of sound: steel vs air
Speed of sound: steel vs air
Steel m/s, Air m/s
P waves (Primary waves) type
P waves (Primary waves) type
Longitudinal seismic waves; travel fastest
S waves (Secondary waves) type
S waves (Secondary waves) type
Transverse seismic waves; slower than P waves
Epicentre
Epicentre
Point on surface directly above underground earthquake focus
Compression (in sound waves)
Compression (in sound waves)
Region where air particles are pushed closer together
