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.

Science Rocks!!
Just imagine living in time before radio waves were discovered. Technology keeps advancing. So much of our lives depend on it today.
If AM varies amplitude and FM varies frequency what the technical reason FM handles static better while AM travels farther?
I never knew what frequency meant before.
I really like the science live classes:)
Is the HAM radio the same or different than a CB radio?
Great live!
Tobias’s lesson on the watch was very interesting!! Love the shirts!
how long can someone stay in space ?
Destiny here, hi from Alabama!!
I love all the colors of the coral! It would be cool to see them in person!
I would want the aviation class it sounds realy nice!!!!!!
I like the parts with R-51 at the end of the science lives. Sometimes they’re very funny.
Thanks for the awesome video. I was wondering two things. One, do people still frequently use the HAM radio and also, who came up with the idea of morse code
this is so cool! okay so is it possible for someone to see radio waves?
Science live is so interesting!
Thank you so much, Dr. Billings. I enjoy your videos.
I think being in space as an astronaut would be awesome. I’d love to see space and radios there
Happy Thanksgiving 🦃 everyone at Acellus. Great motivating science love. I think a class with pilot education would be amazing or a asa extra activity to see how well you can fly with a simulation. I also think Morse code is great to learn so is HAM radio. Also if classes had diy safe things to make at home.
It is amazing that lasers can cool things down!
Thank you so much for this one – my dad said next year we can work on building a radio!
I thought this was going to be boring but it is fun and really cool i am surprised
i love learning with acellus!
Today’s science live was awesome!
We learned about Morse Code last summer – it is so cool!
is it possible for someone to be able to see radio waves?
I liked the part about the robots
This video is awesome I love science live!
My grandparents and great grandparents were both HAM operators. One even had their handle as their license plate.
An aviation course would be awesome!
I did not know a watch would work in outer space. Very cool!!!
Wait, how long astronaut can be in space?
This is one of the most fascinating inventions that I have ever heard and seen! Thank you Acellus for sharing the information and keep inspiring students!
The quantam computer is crazy.
I like the Morse Code part of this video and how it works. I like how you can send different signals through morse code.
This is very educational and helps me get a better understanding, thank you science live!!
What are different types of radio waves and their uses?
Acellus is wonderful!
Thank you ☺️ Happy Thanksgiving
One day my songs will be played over the radio waves
Happy Thanksgiving to everyone at Science Live!
You too happy Thanksgiving
I know I’m late to this one but I was super bust the other week so I wanted to come back and watch this anyways thank you so much for always helping me learn something new and amazing it is truly inspiring
I find it fascinating about the new semi conductors that are being tested right now that will impact our future. It seems that diamonds are a more important stone than just to be used on wedding rings. Science live is so interesting!
Acellus is great!
This is always so fascinating to me, radio waves. I’m glad to finally know what AM and FM radio actually means now!
