Invisible Forces of the Electromagnetic Spectrum

You are constantly using invisible forces to control your world. That song you're

blasting in the car? It's a radio wave carrying music through the air.

When you heat up last night's pizza, you're using microwaves. Sending a text? Your phone is also

using microwaves to communicate. Even changing the TV channel is just you shooting a beam

of infrared light, the same technology used in night vision goggles and camera autofocus.

From radio signals to the light you can see, it’s all part of one big electromagnetic

spectrum, working magic all around you.
