← ScienceWhich limitation arises when transmitting radio waves through ionized plasma?
A)The propagation cut-off frequency✓
B)Increased waveguide mode dispersion
C)Attenuation by stimulated emission
D)Enhanced skin depth transmission
💡 Explanation
Radio waves cannot propagate if their frequency is below the plasma frequency, because the free electrons oscillate and shield the wave (Plasma Oscillation). Therefore, waves at frequencies below cut-off are reflected rather than transmitted through absorption phenomena.
