A ground receiver station is receiving a signal at (a) 6.0 MHz and (b) 110 MHz, transmitted from ground transmitter at a hight of 300 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)`.
