"You mean you don't know? Okay look- this is going to really knock your socks off. So... you know waves, right? Like when you knock a glass of water, they go up and down-" he traces a wave with his finger, "and it turns out, so does the thing we call light. It's sort of like electricity and sort of like a magnet, so we call it electromagnetic radiation. Catchy, no? When this radiation moves in waves that are really big- we're talking the size of buildings here- we call them radio waves, and we use them in radios to hear things along big distances. When the radiation moves in waves that are really small, that's x-rays and gamma rays, like I said. In the middle you have visible light, which is what our eyes can pick up. But they're all the same thing, just with different amounts of energy going through em. Radio is biiiig and sloooow like an elephant, they're low energy, but x-rays and gamma rays are tiny and fast, like a mosquito, they're high energy."
