← ScienceWhich outcome results when a microwave oven's magnetron degrades?
A)Inhomogeneous heating reduces nutrient breakdown.
B)Increased wall reflections cause standing waves.✓
C)Decreased frequency causes uneven vibration.
D)Lower output enables even molecular oscillation.
💡 Explanation
Increased wall reflections lead to areas of high and low energy intensities because of constructive and destructive interference causing a standing wave. This therefore causes uneven heating, rather than a decrease in cooking efficiency under normal conditions.
