← ScienceWhich consequence results when spatially coherent light strikes inhomogeneous glass?
A)Speckle pattern reduces image clarity✓
B)Chromatic aberration distorts perceived colors
C)Snell's law explains increased refraction
D)Fresnel diffraction enhances edge contrast
💡 Explanation
A speckle pattern appears due to constructive and destructive INTERFERENCE of scattered coherent light from refractive index variations. This occurs because wavelets superpose non-uniformly, therefore creating grainy texture rather than uniform illumination or simple refraction.
