WebFor each such layer, there is a frequency, above which if the wave is sent upward vertically, it penetrates through the layer. The function of these layers depends upon the time of the day, i.e., day time and night time. There are three principal layers- E, F1 and F2 during day time. There is another layer called D layer, which lies below E layer. Webinformation is measured at different, horizontally separated positions in the ionosphere. Figure 2.
