← ScienceWhich phenomenon reduces signal strength when electromagnetic waves propagate through a conductive medium containing free electrons?
A)Ohmic losses due to resistive heating✓
B)Constructive interference of scattered waves
C)Faraday rotation of polarization plane
D)Cherenkov radiation emission
💡 Explanation
When EM waves propagate through a conductive medium, free electrons oscillate in response to the electric field component, generating current and causing Ohmic losses because of resistive heating, which dissipates wave energy. Therefore signal strength decreases, rather than the scattered wave interference, plane rotation, energy emission require coherent processes.
