← ScienceWhich outcome results when a microwave oven door seal degrades?
A)Increased wave energy leakage✓
B)Faster food water absorption
C)Resonance chamber shifts frequency
D)Reduced magnetron thermal stress
💡 Explanation
Increased wave energy leakage will occur; the degraded seal allows EM radiation to escape because electromagnetic shielding diminishes, decreasing wave containment. Shielding decreases, therefore leakage increases, rather than alternatives such as thermal stress, which doesn't directly reduce cavity effectiveness.
