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.

    What makes the northern lights appear? What is the lowest wavelength that can be reached?

    Laser cooling is really cool. Using the anti-Stokes principle, atoms can absorb lower-energy light and then re-emit higher-energy photons, allowing them to lose kinetic energy and cool down. It’s so fascinating how precise light manipulation can bring matter to ultra-cold temperatures.

    The subject of a potential aviation class for helicopters reminded of something cool. Leonardo Da Vinci, who I think most people are familiar with, created sketches for a flying machine all the way back during the Italian Renaissance. What’s interesting is that the sketches are very similar in appearance to modern helicopters, and would have operated using the same principles. Is it possible we could see this subject on Science Live someday?

    Not too long ago, researchers announced that diamond turns out to be the best material for semiconductors, although researchers yesterday at the University of Houston think they have discovered a better material – boron arsenite. In their tests, it allowed for more heat to pass through. They also say it is much easier to make than diamond.

    ngl, this episode was really cool. The watch was amazing, espically through all the tests and the way it basically saved the lives on Apollo 13. The cooling lasers was also a really cool thing as well. The fact radio waves can move like a foot every billionth of a second is insane. I never knew it could move that fast. I never really knew much about radios, but the Ham Radio made me more interested in things like this. I love Science Live and I can’t wait to watch in Texas next week!!
