    Radio waves & information transition

    How do radio waves carry the information? I mean the information is digital: 1 or 0, but what is 1 and what is 0 from perspective of radio waves?

    Radio waves propagation & ionosphere

    Guys, thanks a lot for your help. I don't understand the full picture of course, but I understand much more than before :) If you know any good resources where I can find this information, I'd be grateful if you point me there (also interested in this maths that can explain the picture in more...

    Radio waves propagation & ionosphere

    Okay, thanks for your answer. Have one further question: And why the reflecting per se happens? What makes the wave reflecting? Now I understand that the reason is oscillation of electrons with the same frequency, but still don't get why this oscillation changes the direction of the wave..

    Radio waves propagation & ionosphere

    I've read that ionosphere mirrors the short radio waves (25-30 MHz). So 2 questions: Why this happens? There is material on the internet, but it's rather complicated for me so far, I've just started to study physics. So I'd appreciate if someone explains this in more or less simple way. Why...

    Etymology of 'Base': Understand Why It's Called So

    I wonder why bases are called so? In other languages they are named according to the same principles, but I don't get what are they. So why would scientists give a name like 'base' to the respective substance?
