← ScienceWhich consequence arises when a laser beam undergoes speckle formation?
A)Decreased image resolution result.✓
B)Increased laser efficiency is evident.
C)Improved signal-to-noise ratio occurs.
D)Minimized power consumption measured.
💡 Explanation
Speckle formation is caused by the **interference** of coherent light reflecting from a microscopically rough surface; therefore, it reduces image resolution because the speckle patterns distort the image rather than improving its clarity or efficiency rather than alternatives.
