COMEDK · Physics · 31. Communication System
The layer in the Earth's atmosphere which reflects radio waves from the Earth, thus helping radio communication is
- A stratosphere
- B mesosphere
- C troposphere
- D ionosphere
Answer & Solution
Correct Answer
(D) ionosphere
Step-by-step Solution
Detailed explanation
Ionosphere is the ionised part of Earth's atmosphere, which reflects the radiowaves due to total internal reflection towards earth, thus it helps in radio communication.
