What method transmits telephone the simile video and data using electromagnetic waves in the radio frequency above 8990 MHz and below 20 GHz?

Bluetooth
Wi-Fi
Radar
Microwave

The correct answer is: Microwave

The correct method for transmitting telephone, video, and data using electromagnetic waves in the specified frequency range is microwave transmission. Microwaves are a type of electromagnetic radiation with frequencies ranging from about 300 MHz to 300 GHz. The frequency range specified in your question—above 8990 MHz and below 20 GHz—falls well within the microwave range. Microwaves are commonly used in various applications, including telecommunications and data transmission, due to their ability to carry large amounts of information over long distances without significant interference. They can travel in straight lines and are well-suited for point-to-point communication, including satellite and cellular communication systems. To clarify, while technologies like Bluetooth and Wi-Fi also use radio frequencies, they operate at different frequency ranges and are not classified as microwave transmission. Radar operates in the microwave range but is typically used for detecting objects, rather than for the general transmission of telephone, video, and data.
