... charge oscillations. It was shown in [2] that the van der Waals force between a molecule and a surface can become repulsive depending on the relative position of the molecule and the surface resonances. Enhanced scattering due to the resonant excitation of surface charges has also been demonstrated ...

... If another slit, separated from one of the original slits by a distance , is added, how will the intensity at the original peaks change? By examining the phasors for light from the two slits, you can determine how the new slit affects the intensity. Phasors are vectors that correspond to the light ...
