The " backward and forward motions of particles" are always not
simmetric.
The forward is always stronger.

Hello Szczepan .
I see you aren't able to explain "oscillatory flow of electrons" in your
own words.
With " backward and forward motions of particles" I would have asked
"backwards and forwards relative to what" but I suspect that you can't
explain this in your own words.

"More generally, the Stokes drift velocity is the difference between
theaverage Lagrangian flow velocity of a fluid parcel, and the
averageEulerian flow velocity of the fluid at a fixed position. This
nonlinearphenomenon is named after George Gabriel Stokes, who derived
expressions for this drift in his 1847 study of water waves."
