Which effect dominates when monochromatic light encounters nanoscale grating?

💡 Explanation

Constructive interference increases reflection intensity at a specific angle because the path difference between waves diffracted from adjacent grating lines is multiples of wavelengths. Therefore, a strong directional reflectance peak results, rather than refraction or Doppler shift.
