Radio Waves

November 12, 2025  •  EPISODE 286

How do invisible waves travel across the world and beyond? In this episode of Science LIVE, Dr. Roger Billings dives into the fascinating science of radio waves—how they’re created, how they move through space, and how they make long-distance communication possible. From the basics of frequency and transmission to early breakthroughs like Morse code and modern applications such as HAM radio and space communication, join us as we explore the hidden currents that keep us connected.

    I would like a aeronautical class, it will help me with my goal to be a Marine or in the air force.

    When it comes to wearing a watch while in outer space an astronaut I was genuinely surprised to hear that. I knew they needed to take track of time, but thought they had a headset on our an earpiece that helped them communicate with those working with them on earth or just each other. Never really dived into that so knowing this now is cool.

A watch that can withstand all the vibration, extreme temperatures, and vaccum like conditions is pretty cool! It’s so scary to think that if they miscalculated something by one second it could be disastrous! Thanks, learning about these things are very interesting! ~~

    I would really enjoy a morse code class! I definitely would use it as a real world skill and talk to my friends and family. I hope Dr. Billings decides to make it into a course, along with a ham radio class!
