← ScienceWhich outcome occurs when imperfections cause beam overlap in holography?
A)Speckle pattern degrades image quality✓
B)Constructive interference enhances contrast
C)Polarization shifts reduce reconstruction
D)Diffraction fringes become more distinct
💡 Explanation
Speckle pattern degrades quality in holography because **interference** from scattered light interacts; forming grainy patterns. Therefore image loses clarity, rather than improved due to uniform constructively interference patterns.
