A ground receiver station is receiving a signal at 8 MHz , transmitted from ground transmitter at a hight of 289 m located at  a distance of 100 km. Identify whether it is coming via space wave or sky wave propagation or satellite transponder. Radius of earth `= 6.4 xx 10^6m`. Maximum number density of electrons in ionosphere `= 10^(12)m^(-3)`.
