Which atmospheric layer causes reflection of radio waves and makes long wave radio communication possible?
Which atmospheric layer causes reflection of radio waves and makes long wave radio communication possible?
Show Hint
The ionosphere reflects radio waves; remember ”Ionosphere = Ionized for radio.”
Updated On: Jan 13, 2026
- Thermosphere
- Ionosphere
- Mesosphere
- Stratosphere
Show Solution
The Correct Option is B
Solution and Explanation
The ionosphere's ions and free electrons reflect and refract radio waves Earthward, facilitating long-distance radio communication. This layer is critical for High Frequency (HF) radio transmissions.
