I know that when a Longitudinal (Sound) Wave spreads in water the displacement
of the water particles is parallel to the direction of wave propagation and the displacement
equation looks like this :
y(x,t)=A*sin[2*π*f*(t-x/u)]
where : A=Amplitude, π=3.14..., f=frequency, u=speed of wave propagation
If i have diffused in the water some other particles, lets say sand, how will the particles
of the sand oscillate? I think the displacement should be also an equation like y(x,t)=...
but now it has to be a function of M (mass), maybe V(volume) and D(particle diameter)
as well.I believe that if a Longitudinal wave reaches a rock of D=5 cm displacement of
rock will be almost zero, but if it reaches a particle of D=1.e-07 m displacement will not
zero.
If you have any ideas, please reply.
