← ScienceWhich consequence results when standing waves form within a microwave oven cavity?
A)Uneven heating of the food✓
B)Localized decrease in input power
C)Reduced magnetron tube lifetime
D)Overall decrease in microwave frequency
💡 Explanation
Uneven heating emerges because standing waves cause constructive and destructive interference. This interference creates regions of high and low energy; therefore, some regions overheat rather than uniform heating which requires proper mode-stirring.
