← ScienceWhich outcome arises when mismatched dielectric constants impede wave propagation?
A)Increased signal reflection and interference✓
B)Improved impedance matching, less loss
C)Waveguide resonance stabilizes signals
D)Reduced antenna gain and directionality
💡 Explanation
Impedance mismatch means that not all incident power is transmitted; significant signal reflection and interference occur because the transmission line experiences standing waves due to wave reflection, therefore reduces the signal strength, rather than complete power delivery.
