1: You can set anything flammable on the ground and start a fire on it, as long as it's not indoors. If it's indoors you'll set the whole place on fire, but outdoors just drop a piece of wood on the ground and it'll burn just fine.

Electromagnetic radiation is just a moving wave of electric and magnetic energy. ... For the Internet, we use computers as a source to generate and receive this electromagnetic radiation. Cables that connect our phones (and TV's) are used to transmit the radiation from one computer to the next to transfer information.
