← ScienceWhich outcome occurs when a high-frequency electromagnetic wave propagates through plasma?
A)Wave undergoes frequency-dependent dispersion.✓
B)Wave maintains coherent beamwidth indefinitely.
C)Increased plasma temperature halts propagation.
D)Waveguide modes cause efficient transmission.
💡 Explanation
Frequency-dependent dispersion occurs because the wave's interaction with ions causes a differential slowing based on frequency components, therefore, different frequencies arrive at different times resulting in pulse spreading, rather than coherent transmission.
