← ScienceWhich outcome occurs when a microwave cavity exceeds saturation energy?
A)Frequency shifts distort wave propagation
B)Decreased Q factor damps oscillation
C)Increased capacitance stores excess energy
D)Dielectric breakdown generates plasma✓
💡 Explanation
Dielectric breakdown occurs because exceeding the threshold field causes ionization; this generates conductive plasma, shorting the field, therefore wave transmission breaks, rather than frequency distortion because that requires slow change in geometry.
