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.

How does this effect the watch?
dr johns story was cool
Hey from Tennessee! 😃
Me too, woohoo! another Tennessean!
What were the watches made out of to withstand all of that beating!?

I have a saltwater fish aquarium filled with fluorescent coral and I love how the black light shows all the different neon colors.
how long did they take to make astronaut suits??
Did the guy use a Rolex?
Dr. John, this is so interesting, I never knew that lasers could be that interesting

Tobias is great to listen too!
Loving science livee
I love the science live! Its always so interesting
Hello Dr. John, is this new laser-cooling technology capable of not only cooling but actually freezing things?
Seeing the Northern lights is awesome
if we can get to the moon, are we planning to expand humanity to different planets?
That’s unusual, who knew that you could you a laser to cool things down: the opposite of what you’d think!
I love Science Live, it’s so informative.
I LOVE ACELLUS
Science live rocks
Coral is such an incredible organism! It is crazy that something so complex seems so simple at a glance.
I really love learning and Acellus makes in funn.
I love fluorescent colors. So bright 🥰
Science is amazing!!
Hello I am from San Antonio, Texas as-well, as others have stated too! I am an 8th grader in Acellus! I would like to see more about space and computer technology!
Interesting. You are my favorite teacher dr john
wow i didnt know that lasers can cool stuff
Here from Nebraska i wonder if you could use the laser cooling for fires
Science is SO wonderful !!!!!!!!!!!
Hey from Tennessee
tech spotlight is great
Hello, from Idaho! These lives are the highlight of my week.
That’s insane how lasers can cool stuff. : ]
How big are these lasers to cool the chips? I would imagine that the lasers would be extremely small.
What is the strongest metal that a laser can actually cut through?
Hi! I love the ✨ colors ✨ in the little jars 💛🩵

I LOVE SCIENCE LIVEEEEEEEEEE 🙂 🙂 🙂 🙂 🙂 🙂
I heard blue light is bad for us and red light is good for us, I would love to hear your thoughts!
I have always loved watching your lessons on science live!
What makes these corals interesting is that they’re florescent and can change colors depending on the light. This is a really great episode! 🙂
Do the hammer corals have strong protection?
How many bioluminescent coral species are there?
How many different florescent colors are there?
Those are beautiful corals.

Hi from North Carolina!!
Anyone else from Maine??!! We love science live!!!!
Hello from Florida! I have a question for Dr. Billings: What advice would you give an aspiring teen scientist who may not have access to all the materials they need to work on the invention of their dreams? How can we work on our creativity and use what we have to design something?
those are some nice coral colors and its awesome how they change color.
Coral is so pretty!!!
I never knew lasers could cool things down or florescent coral exists!
My mommy likes that she can see how far I am from completing a class.
I never thought lazers could cool things!
Wow those colors are gorgeous!
Why does the coral have different colors?
The coral colors remind me of the movie Avatar!
I didn’t know you could use lasers to cool stuff down, that’s cool
I didn’t know that lasers can cool things
Making an intentional space between learning periods is so crucial to information retention. I find that I am able to learn so much more when I spread out my learning into specific incriments and let the information settle compared to cramming a larger amount of information into a shorter amount of time.
Hello from North Carolina! I love being here every week! Which section(s) is(are) your fav? I really like the tech spotlight!
I always thought that chunking and consistently studying is better than cramming. I am happy to hear that. I love the analogy of studying and working out in the gym. When we work out, consistent workouts build muscle, therefore consistent studying helps enhance learning.
I….LOVE ………….ACELLUS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
those are biolumenescent aren’t they
The coral that Dr. John was talking about is so beautiful.
Hello! I’m from MO I love science live!!!

Using Lazers to COOL things down, now this’ll be intriguing. 🤔
I wonder how cool a laser can get.
So beautiful that there are northern lights in Florida. I am excited to watch this live science.
I never really knew that lasers were able to cool things!
Science is my favorite subject !! Makes me wanna learn more !!!
