particle motion / oscillations are parallel
to direction of wave propagation
Longitudinal
particle motion / oscillations are
perpendicular to direction of wave propagation
transverse
v= (upside down Y) f
wave speed for wave propagation speed
distance per time
m/s
propagation of a twisting motion
torsional waves
seismic surface waves
love (ore damage) and rayleigh
tend to be combination of transverse and longitudinal waves
water waves
a wavelength and period (or frequency)
EM waves electromagnetic waves
single pluse
photon
Electromagnetic waves with frequencies higher than the visible part of the spectrum are said to be
ionizing
