The website offers 10 fun ways to celebrate the day, an infographic about youth and radio, links, and graphics such as banners, logos, and posters.

As we have seen with TV and movies, radio is becoming more and more of a “streaming” thing in addition to a “broadcast” thing.
We can enjoy niche stations that only interest a small minority of people.
We can create our own content and upload it to Soundcloud.
It would seem to make sense that radio waves would be a kind of sound wave, but no. Actually, radio waves are more like visible light!
Visible light and radio waves, along with things like infrared, ultraviolet, microwaves, and X-rays, are all forms of electromagnetic radiation. They all travel through a vacuum (essentially empty space, without air) at what we call the speed of light. Radio waves are much, much bigger than light waves (in terms of their wavelength).

Of course, our radios are designed to snatch radio waves and turn them into sound!
It isn't just AM/FM radios and ham radios that use radio waves; cordless phones, garage door openers, cell phones, TV remotes, remote-controlled toys, GPS devices, satellite transmissions, WiFi, and airplane controls all use radio waves.
