← ScienceWhich effect appears when nanoscale metallic gratings diffract light?
A)Surface plasmon resonance occurs intensely✓
B)Brewster's angle becomes nearly 90°
C)Chromatic aberration gets fully cancelled
D)Raman scattering disappears entirely
💡 Explanation
When light diffracts off nanoscale metallic gratings, surface plasmon resonance is strongly excited because incident photons drive coherent oscillations in the metal's electrons. Therefore, increased resonance occurs, rather than altered polarization or scattering effects.
