Anonymous @ on Square of electric field and process used Can
anyone explain how can we calculate the magnitude of electric
field at a point on the surface of a gold/silver particle? We
can simulate the square of electric field and we get a color
mapping of it with the scale at the bottom. But how can we
exactly make out with color shade is it compared to scale at
that point. Moreover the magnitude numbers shows below on the
scale, what are its units? what are those numbers taken in
reference to?
