← ScienceWhich mechanism causes signal distortions when millimeter waves propagate?
A)Atmospheric multipath electromagnetic interference✓
B)Material induced frequency resonant disruption
C)Dispersion-induced amplitude broadening
D)Quantum entanglement phase decoherence
💡 Explanation
Atmospheric multipath interference causes signal distortion, because reflections interfere constructively and destructively; therefore power fluctuates causing error rather than dispersion which affects pulse length and is fixed unless tuned.
