Bluetooth is a network technology that connects mobile devices wirelessly over a short range to form a personal area network (PAN). They use short-wavelength, ultra-high frequency (UHF) radio waves within the range of 2.400 to 2.485 GHz, instead of RS-232 data cables of wired PANs. Features of Bluetooth Bluetooth technology was released in 1999 as Bluetooth 1.0, by the Special Interest Group (SIG) which continues to manage it. It was initially standardized as IEEE 802.15.1. Mobile computing devices and accessories are connected wirelessly by Bluetooth using short-range, low-power, inexpensive radios. UHF radio waves within the range of 2.400 to 2.485 GHz are using for data communications. A PAN or a piconet can be created by Bluetooth within a 10 m radius. Regards, Peter

Electromagnetic waves, kind of like radio waves or microwaves.

By Internet waves, one would assume you mean WiFi. When talking about WiFi, it does not use electromagnetic waves but instead uses radio waves like your TV or radio does.
your mum :D
Radio waves (along with magnetism) are used for that purpose instead of x-rays in MRI machines. x-rays are absorbed by the body differently than radio waves, so it depends on what in the body is being looked at.
By using radio waves.
"Radar" comes from RAdio Detection And Ranging. If it didn't use radio it would be called something else.LIDAR (LIght Detection And Ranging) is laser instead of radio. That uses light.
Most of these networks use radio waves for their transmission medium, but some use infrared light waves
