    Radio waves, microwaves, and infrared waves are commonly used for telecommunication.

    1. Radio Waves: These have relatively long wavelengths and are commonly used for radio and television broadcasting. They are also used for wireless communication, including Wi-Fi and Bluetooth.

    2. Microwaves: Shorter in wavelength than radio waves, microwaves are utilized in various communication technologies, such as satellite communication and microwave ovens. They’re also the basis for many forms of wireless communication, including certain types of mobile networks.

    3. Infrared Waves: Slightly shorter in wavelength than microwaves, infrared waves are often used for short-range communication, such as remote controls for TVs and other devices. Infrared is also employed in some data transfer technologies.

    All these waves are part of the electromagnetic spectrum, and their specific use depends on factors like range, data transfer rate, and the nature of the communication system.
