Question:
Long distance short wave radio broadcasting uses
Long distance short wave radio broadcasting uses
Show Hint
Shortwave radio travels long distances via ionospheric reflection.
Updated On: Jul 2, 2026
- ground wave
- direct wave
- ionospheric wave
- space wave
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Radio wave propagation methods depend on frequency and distance.
Step 1: Ground wave Suitable for low frequencies and short distances.
Step 2: Space wave Used for line-of-sight communication.
Step 3: Ionospheric wave Reflected by ionosphere enabling long distance communication.
Step 4: Short wave broadcasting Uses ionospheric reflection for global reach.
Step 5: Conclusion \[ \boxed{\text{Ionospheric wave}} \]
Final Answer: \[ \boxed{(C)} \]
