* Television: The radio's ability to transmit sound waves over long distances paved the way for the development of television, which added visual information to the audio.
* Radar: Radar uses radio waves to detect objects by reflecting them off of them. This technology is used in a variety of applications, including air traffic control, weather forecasting, and military operations.
* Cell phones: Cell phones combine the radio's ability to transmit sound waves with the cellular network's ability to connect devices to each other. This allows cell phones to make and receive calls, send text messages, and access the internet.
* Wireless networks: Wireless networks use radio waves to connect devices to each other without the need for cables. This technology is used in a variety of applications, including Wi-Fi networks, Bluetooth, and NFC.
* Satellite communications: Satellites use radio waves to communicate with each other and with devices on Earth. This technology is used for a variety of purposes, including television broadcasting, weather forecasting, and military operations.
* Navigation and positioning systems: Radio waves can be used to determine the location of objects by using triangulation or by measuring the time it takes for a radio signal to travel between two points. This technology is used in a variety of applications, including GPS navigation, marine navigation, and surveying.
