← ScienceWhich consequence results when a laser beam encountering a non-homogenous medium?
A)Speckle pattern interferes with image✓
B)Complete transmission without any scattering
C)Increased gain within optical parametric oscillator
D)Reduced chromatic aberration with shorter pulses
💡 Explanation
A speckle pattern emerges because constructive–destructive interference occurs when coherent light scatters off an irregular medium; therefore the image quality decreases, caused by multiple path lengths, rather than perfect beam transmission effects or parametric oscillations.
