Science

Which mechanism causes increased reflection at dielectric interfaces for specific wavelengths?

A)Brewster angle polarization
B)Bragg diffraction condition
C)Critical angle extinction
D)Anomalous dispersion resonance

💡 Explanation

Increased reflection for specific wavelengths occurs via Bragg diffraction condition, because constructive interference amplifies reflected waves when the wavelength satisfies Laue's equation; therefore intensity rises sharply, rather than continuous polarization or total extinction.
