Question
Which range of Frequencies is Suitable for sky wave Propagation ?(A) $1 \mathrm{KHZ}$ to $500 \mathrm{KHZ}$(B) $1 \mathrm{MHZ}$ to $2 \mathrm{MHZ}$(C) $2 \mathrm{MHZ}$ to $20 \mathrm{MHZ}$(D) Above $30 \mathrm{MHZ}$
Step 1
Sky wave propagation is a method of signal transmission in which the signal is sent from the transmitter to the ionosphere and then reflected back to the receiver on the earth. This method is used for long-distance communication. Show more…
