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?
