Vedclass · Answer

(C) The critical frequency $(f_c)$ of the ionosphere is the highest frequency that can be reflected by the ionosphere at vertical incidence.It is related to the maximum electron density $(N_{max})$ by the formula:$f_c = 9 \sqrt{N_{max}}$where $f_c$ is in Hertz $(Hz)$ and $N_{max}$ is in electrons per cubic meter $(m^{-3})$.Thus,the correct option is $C$.

The relationship between the maximum electron density $(N_{max})$ of the ionosphere and the critical frequency $(f_c)$ is given by:
