← ScienceWhich outcome occurs when a radio antenna broadcasts at resonance?
A)Maximum electromagnetic wave emission✓
B)Minimum standing wave formation
C)Decreased impedance matching to source
D)Reduced efficiency of power amplification
💡 Explanation
Resonance causes maximum energy transfer via constructive interference, because the Reactance approaches zero, increasing electromagnetic wave emission. Therefore, emission is maximized, rather than lower wave power because destructive interference decreases energy emitted.
