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
Answer:
300 is the answer

Hope that this answer will help you
Answer:
Red, Green, and Blue
Explanation:
Each of the pixels on a computer monitor or TV screen is composed of phosphors surrounded by a black mask. The different colors we see are results from different combinations and intensities of these three primary colors (Red, Green, and Blue).
Answer:NO
Explanation:
No, because as it swings it is mechanical energy that changes from almost completely potential energy to almost completely kinetic energy and thermal and sound.
