So what's new? (Score -1)

"Plasmons are generated when, under the right conditions, light strikes a metal. The electric field of the light jiggles the electrons in the metal to the light's frequency, setting off density waves of electrons." Sounds to me like "plasmons" is just a different way of saying "electromagnetic radiation". Its just at different frequencies than visible light (x-rays, gamma rays, radio, etc.) Or maybe I am confusing waves of photons with waves of electrons. But then what is the difference between plasmons and regular, good old-fashioned-Ben-Franklin-zapping electricity?
