← ScienceWhich outcome arises when coherent laser light reflects off closely spaced grooves?
A)Diffraction causes distinct intensity maxima.✓
B)Refraction decreases beam divergence.
C)Absorption causes significant heating.
D)Emission boosts photon amplification gain.
💡 Explanation
Diffraction gratings cause interference, which results in constructive and destructive interference patterns. Constructive interference concentrates light along specific directions. Dark bands form elsewhere because destructive interference diminishes intensity rather than spreading it.
