Question:
The medium which reflects high frequency radio waves back to the earth’s surface is called _______.
The medium which reflects high frequency radio waves back to the earth’s surface is called _______.
Show Hint
The ionosphere plays a key role in radio wave propagation due to its ionized gases.

- Biosphere
- Stratosphere
- Troposphere
- Ionosphere
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The ionosphere contains charged particles (ions) that reflect high-frequency radio waves. This layer lies approximately 50–600 km above the Earth's surface and is crucial for long-distance radio communication.
Other options:
Biosphere: Region containing life, unrelated to wave reflection.
Stratosphere: Contains the ozone layer, not involved in radio wave reflection.
Troposphere: Lower atmosphere, affects weather, not radio propagation.
