Which outcome occurs when a microwave oven's magnetron fails?

A)Uneven heating throughout the food
B)Reduced radio frequency interference
C)Cavity resonance shifts downward
D)Increased waveguide power transmission

💡 Explanation

When the magnetron weakens, microwave production becomes inconsistent, leading to uneven heating because electromagnetic energy distribution fluctuates rather than maintaining a uniform standing wave. Therefore some areas are cold, rather than heat evenly given consistent microwaves.
