← ScienceWhich outcome occurs when a laser printer's coherence degrades?
A)Speckle noise increases in prints
B)Toner deposition becomes highly localized
C)Print resolution appears lower✓
D)Optical trapping exerts greater force
💡 Explanation
Decreased spatial and temporal coherence leads to fuzzier laser spots. The **interference** creating sharp beam edges fails, which makes toner placement less precise overall, blurring details. Therefore, image resolution decreases rather than the laser beam providing greater focus.
