The radio waves travels between the two boxes and they were travelling through air,
- Box B captures, amplifies and demodulates radio waves.
- Box A modulates, amplifies and send out radio waves.
<h3>What are radio waves?</h3>
- Radio waves are the type of radiation from the electromagnetic spectrum.
- The radio waves can be used in communication technologies like computer, phones, radios , etc..
- Radio waves have lower frequencies but longer wavelength.
- These devices will get signal and then it transmit as mechanical waves through sound.
In that way, the radio waves from box A to B through air, the box A will gets the signal, and then modulates, amplifies and then it send out radio waves. Through the air, Box B will captures, amplifies and demodulates radio waves.

-- The acceleration of gravity (on Earth) is 9.8 m/s².
-- That means that during every second an object falls,
it adds 9.8 m/s of speed.
Now ! If it adds 9.8 m/s of speed every second, then
how fast is it falling at the end of 3.4 seconds ?
This is as close as I can bring you to the answer
without dropping it at your feet, or handing it to you
on a golden tray.
