Answer:
Index of refraction=Angle of incidence/Angle of refraction
=5/2.1
=2.38
The best answer between the two options would be the second choice B) FALSE.
The answer is zero hope I helped
By definition,
q = 1.22y/D
Where,
q = min. angle
y = wavelength
D = Aperture diameter = diameter of the antenna
At distance "x" from the antenna,
L =xq = 1.22xy/D
Where, L = Min. distance
But, y =c/f = (3*10^8)/(16*10^9) = 0.01875 m
Substituting;
L = 1.22*5*10^3*0.01875/2.1 = 54.46 m
That's "displacement". It only depends on the beginning and ending locations, and doesn't care about the route between them.
