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.
