← ScienceWhich field interference results when radio waves reflect?
A)Multipath signal fading increases greatly✓
B)Antenna impedance matching becomes stable
C)Transmitter power amplification loses efficiency
D)Receiver sensitivity threshold decreases slightly
💡 Explanation
When reflected radio waves interfere, multipath fading occurs; this is due to constructive and destructive interference, because these signals arrive out of phase. Therefore, signal fading increases, rather than impedance matching or increased receiver sensitivity, due to the variation in field strength.
