The maximum frequency of transmitted radio waves above which the radio waves are no longer reflected back by ionosphere is (N = maximum electron density of ionosphere, g = acceleration due to gravity)

Height h(400=m) from the ground at place A, from which the readiowaves can be transmitted. There is a receive at station B on earth at a distance d(=125km), which can receive the signal from station A. The radiowaves can reach the station B, either through earth's atmosphere or through satellite. There are four main layers in earth's atmosphere named D,E, F_(1) and F_(2) which play effective role in radio communication. The electron density of these layers is 4xx10^(8), 2xx10^(11),5xx10^(11) and 8xx10^(11)m^(-3) . The radius of the earth is 6.4xx10^(6)m . On a particular day, the maximum frequency reflected from the ionosphere is 9 MHz. On another day, it was found to increase by 1 MHz.
