Question

Solve the following, if the radio wave transmitted at an angle of incidence 68 degrees, with a wavelength of 6mm.
I. Find the critical density 
II. Find Maximum usable frequency if Nmax = 2xN Critical

Expert Solution
Step 1

Given:

   Angle of incidence, θ = 68°

   Wavelength, λ = 6 mm = 6 × 10-3 m

   Frequency, f = cλ

             f =3 × 108 m/s6 × 10-3 m      f = 5 × 105 Hz

Step 2

a) Relation between critical density, Nc and frequency, f is given as follows :

          f = 9 Nc  Nc = f 29 2     Nc =  5 × 105 281               Nc = 0.3086 × 1010 m-3
