A ground receiver station is receiving a signal at

100 \mathrm{~MHz}

, transmitted from a ground transmitter at a height of

300 \mathrm{~m}

located at a distance of

100 \mathrm{~km}

. Then,

\left(N_{\max}=10^{12}\right.

per

\left.\mathrm{m}^3\right)

View answer and explanation

Correct option: C

Signal is coming via satellite transponder

Option C is correct. The signal is coming via satellite transponder because the distance exceeds the range for space wave communication and the frequency is too high for ionospheric propagation.
