← ScienceWhich outcome results when a radio wave encounters a conductive wire that exceeds its skin depth?
A)Radio wave is exponentially attenuated✓
B)Resonance creates standing wave amplification
C)Wavefront experiences total internal reflection
D)Wave propagates at increased phase velocity
💡 Explanation
When the conductive wire exceeds the radio wave's skin depth, the electromagnetic field induces eddy currents that experience Ohmic loss via resistive heating because the skin effect causes exponential attenuation of the radio wave within the conductor, therefore the energy is dissipated, rather than propagating or reflecting.
