← ScienceWhich consequence results when ground reflections interfere in microwave transmission?
A)Signal nulls due to destructive interference✓
B)Increased signal strength from constructive interference
C)Frequency shift because of Doppler effect
D)Polarization rotation reduces antennae gain
💡 Explanation
Signal nulls occur because destructive interference leads to cancellation of direct path and ground-reflected waves during propagation. The reflected wave inverts upon ground reflection, creating a phase difference that can weaken the overall resultant, rather than producing signal amplification.
