(D) Microwave

Microwaves are used for satellite communication. They are a type of electromagnetic wave with a wavelength range between one millimeter and one meter, corresponding to frequencies between 300 MHz (megahertz) and 300 GHz (gigahertz). These waves are suitable for long-distance communication as they can travel in straight lines through the atmosphere and space without significant interference. Satellites use microwave signals to transmit and receive data, allowing for various applications such as television broadcasting, internet connectivity, weather monitoring, and global positioning systems (GPS).
