The following two frequencies (f1 and f2 ) are related to ionospheric sky wave propagation : f1 = 17 MHz , f2 = 5 MHz. One of them is the maximum frequency returned by the ionosphere when the waves are transmitted vertically upwards, and the other is the maximum frequency returned by the ionosphere at zero take-off angle. Name these two frequencies f1 and f2 . Also calculate the height of the F layer for these pair of frequencies.
