← ScienceWhich outcome occurs when a signal propagates down a long, unterminated transmission line?
A)Signal experiences minimal attenuation
B)Wave exhibits increased self-interference✓
C)Capacitance of line reaches minimum
D)Line radiates all input energy
💡 Explanation
The wave undergoes reflection because of impedance mismatch at the unterminated end, leading to increased *constructive and destructive interference*. Therefore, enhanced self-interference is observed, rather than complete radiation which needs an antenna structure.
