What two everyday devices use radio waves?
Cellphones and walkie-talkies are two everyday devices that use radio waves. Radio waves are a type of electromagnetic radiation that travel through the air and can be used to transmit sound or data.
Cellphones use radio waves to communicate with cell towers. When you make a phone call, your cellphone sends a radio signal to the closest cell tower. The cell tower then sends the signal to the person you are calling.
Walkie-talkies also use radio waves to communicate. They work in a similar way to cellphones, except that the walkie-talkie sends a signal directly to the other walkie-talkie. This is why they are often used by police officers and firefighters.
