← ScienceWhich outcome occurs when a microwave oven's waveguide is deformed?
A)Uneven heating of the food✓
B)Increased cooling fan output
C)Higher magnetron tube voltage
D)Suppressed carousel motor current
💡 Explanation
Deformation alters internal geometry causing mode conversion, whereby specific resonance frequencies distort the microwave distribution pattern because standing waves amplitude distributions deviate from design, therefore uneven heating rather than uniform heating occurs, suppressing motor activity remains unrelated.
