Bluetooth is a wireless communication technology that uses radio waves, not microwave radiation. Specifically, Bluetooth operates within the frequency range of 2.4 GHz to 2.4835 GHz. This frequency range falls within the microwave spectrum, but it is important to note that Bluetooth itself does not use microwaves as a form of communication.
Bluetooth technology is designed for short-range communication between devices, typically within a range of about 10 meters (30 feet). It enables wireless connections and data transfer between devices such as smartphones, tablets, laptops, headphones, and other peripherals. Bluetooth signals are transmitted using radio waves, which are a type of electromagnetic radiation. Radio waves have longer wavelengths and lower frequencies compared to microwaves.
The name "Bluetooth" is derived from the 10th-century King Harald Bluetooth of Denmark, who united different tribes and regions, symbolizing the technology's purpose of uniting different devices and facilitating communication between them.
