Progressive Waves


Earthquakes produce 2 main P
types of seismic waves waves

and S -
waves


P -


waves are longitudinal} both are
progressive
S waves are

transverse waves -




Progressive wave : an oscillation that travels
through matter ( or

in some cases a vacuum
) .
all
transfer energy
but not matter .




Particles in a medium more about their equilibrium position .




A displaced particle experiences
it back
a
restoring force from its

neighbours pulling ,
to its
original position .




Transverse waves have oscillations that are perpendicular to the
direction Transverse waves have peaks
