Answer:
 λ₁ = 2.50 10⁻² m,   λ₂ = 1.66 10⁻² m   
Explanation:
Microwave communication is very efficient because it does not have atmospheric interference, for which it is widely used and has been regulated to avoid interference, the ku band is in the range between 12 and 18 GHz.
Let's calculate the wavelength for the two extreme frequencies of this band
 wavelength and frequency are related
          c = λ f
           λ = c / f
f₁ = 12 GHz = 12 10⁹ Hz
           λ₁ = 3 10⁸ /12 10⁹
            λ₁ = 2.50 10⁻² m
f₂ = 18 GHz = 18 10⁹ Hz
           λ₂ = 3 10⁸ /18 10⁹
           λ₂ = 1.66 10⁻² m
Unfortunately in your exercise the specific frequency is not fired, for significant figures they must be the same number as the figures of the frequency, in general the frequency has 3 or 4 significant figures
 
        
             
        
        
        
Here, E<span>ach kilogram of mass weighs 9.8 newtons as it's unit value of it.
In short, Your Answer would be Option D
