← ScienceWhich risk increases when a microwave waveguide sustains damage?
A)Arcing and mode conversion occur✓
B)Reduced transformer core saturation level
C)Amplified Doppler frequency measurement uncertainty
D)Increased dielectric strength of coolant fluids
💡 Explanation
Arcing and mode conversion both become far more likely, caused by surface discontinuities triggering increased electromagnetic field magnitudes. Wave interference then distorts mode properties because impedance mismatches intensify near the damaged interface; therefore arcing damage results, rather than changes fluids or irrelevant transformer effects.
