← ScienceWhich phenomenon causes signal degradation as electromagnetic wave propagates through a lossy dielectric material?
A)Ohmic losses generating heat reducing amplitude✓
B)Increased wave velocity causing refractive distortion
C)Interference creating standing waves cancelling signals
D)Resonance amplifying harmonic frequencies
💡 Explanation
As a wave propagates through a lossy dielectric material, ohmic losses occur because the electric field component induces current, resulting in heat dissipation, and thus reducing the wave's amplitude. Therefore signal degradation via ohmic heating arises, rather than refractive distortion, interference, or amplification, which arise from different material properties or wave interaction conditions.
