Given,

Maximum ionic density (Nmax)=2.3×104/cc(N_{max})=2.3\times 10^{4} /cc

Critical frequency (fc)=9Nmax(fc)=9\sqrt{N_{max}}

Now, substituting the values,

fc=92.3×104×106f_c=9\sqrt{2.3\times 10^{4}\times 10^{6}}

fc=9×1.51×102×103\Rightarrow f_c=9\times 1.51\times 10^2\times 10^3 Hz

fc=13.6×105Hz\Rightarrow f_c=13.6\times 10^5Hz

fc=1.36MHz\Rightarrow f_c=1.36MHz
