Answer:
Low Frequency, Long Wavelength, and Low Energy Transfer
Explanation:
Radio waves are on the larger(and lower frequency) side of the electromagnetic spectrum. These longer wavelengths mean that radio waves have a lower frequency because it takes longer for larger waves to travel. Therefore, less radio waves can travel a certain distance in a minute than a wave of a shorter wavelenght(and therefore lower frequency). Radio waves are considered a low-energy transfer wave. This is because they can be used in most environments for communication, air-traffic control, and broadcasting with little to no harm to the organisms around them. Even though radio waves can be found all around us, because they don't carry much energy, we aren't harmed by the radio waves.

The true statement about the directrix is that each directrix of this ellipse is 31.25 units from the center on the major axis.
<h3>How to determine the distance of the directrix?</h3>
The equation of the ellipse is given as:

The above means that:
a^2 = 625
a = 25
b^2 = 225
b = 15
Calculate c using:
c^2 = a^2 - b^2
This gives
c^2 = 625 - 225
Evaluate the difference
c^2 = 400
Evaluate the square root
c = 20
The equation of the directrix is
x - x₀ = ± a²/c
So, we have:
x - x₀ = ± 625/20
Evaluate the quotient
x - x₀ = ± 31.25
This means that, each directrix is 31.25 units from the center on the major axis.
