* Radio and television broadcasting: Radio waves are used to transmit radio and television signals over the air. These signals are picked up by antennas on our radios and televisions, allowing us to listen to music, watch news and entertainment programs, and stay informed about current events.
* Mobile phones: Radio waves are used to transmit voice and data signals between mobile phones and cell towers. This allows us to make phone calls, send text messages, and access the internet on our mobile devices.
* Wireless internet: Radio waves are used to transmit data between wireless routers and devices such as computers, smartphones, and tablets. This allows us to connect to the internet without having to be connected to a physical cable.
* Garage door openers: Radio waves are used to open and close garage doors. When we press the button on our garage door opener, it sends a radio signal to a receiver in the garage door, which then opens the door.
* Keyless entry systems: Radio waves are used to unlock doors without a key. When we approach a door with a keyless entry system, a sensor detects our key fob and sends a radio signal to a receiver in the door, which then unlocks the door.
