Which consequence results when laser light encounters multiple subwavelength slits?

A)Extraordinary optical transmission occurs
B)Total internal reflection decreases
C)Fresnel diffraction fringes vanish
D)Raman scattering becomes suppressed

💡 Explanation

Extraordinary optical transmission occurs because surface plasmon polaritons are excited by the incident laser light and resonantly transmit through the otherwise opaque metal via plasmonic resonance, therefore enhanced transmission, rather than simple diffraction, is observed at certain resonant frequencies.
