-
Medium wave radio signals may be received at for distance at night because—
-
- Radiowaves travel faster at night
- Ground wave attenuation is low at night
- The sky wave is stronger at night
- Their is no fading at night
Correct Option: C
Propagation in medium wave frequency 525 to 1625 kHz is absorbed by D layer during day time. This vanishes at night and E layer helps in reflection at night especially at the higher range of frequency.
