प्रश्न
Answer the following question.
On what factors does the range of coverage in ground wave propagation depend?
उत्तर
The ground wave propagation is preferred usually for long-distance communication using frequencies below 3 MHz. The range of coverage of ground wave propagation depends on transmitted power and frequency.

The maximum frequency for reflection of sky waves from a certain layer of the ionosphere is found to be fmax = 9(Nmax)1/2, where Nmax is the maximum electron density at that layer of the ionosphere. On a certain day, it is observed that signals of frequencies higher than 5 MHz are not received by reflection from the F1 layer of the ionosphere while signals of frequencies higher than 8 MHz are not received by reflection from the F2 layer of the ionosphere. Estimate the maximum electron densities of the F1 and F2 layers on that day.
