← ScienceWhich outcome occurs when radio waves encounter significant atmospheric ionization?
A)Shortwave radio signal propagation improves✓
B)Tropospheric ducting propagation decreases
C)Radio telescopes detect increased stellar noise
D)Microwave link attenuation becomes stronger
💡 Explanation
Shortwave signal propagation is achieved through ionospheric reflection, because the increase in ionization enhances this reflection mechanism. Stronger shortwave reflection leads to improved signal reach; therefore shortwave communication becomes easier, rather than tropospheric or microwave propagation alterations.
