← ScienceWhich optical consequence results when laser light encounters imperfections within crystal?
A)Speckle pattern forms due scattering.✓
B)Chromatic aberration significantly reduces.
C)Fresnel diffraction dominates imaging.
D)Total internal reflection efficiency peaks.
💡 Explanation
A speckle pattern occurs due to the constructive and destructive interference from coherent laser light scattering off the rough surfaces. This phenomenon, known as laser speckle, arises because the path length differences are on order of wavelength; therefore it causes the answer, rather than others related to refractive properties under ideal conditions.
