it doesn't, it uses microwaves
bluetooth is an open wireless protocol for exchanging data over short distances. it uses short length radio frequencies. bluetooth uses a radio technology called frequency-hoping spread spectrum.
RADAR (RAdio Detection And Ranging)
Wireless.
One uses infrared light and the other uses radio waves. Hope this helps!

it uses radio waves
Yes. A good rule of thumb is that if the device has an antenna, it uses radio waves. An antenna would not be needed if it didn't use radio waves.

Radar uses radio waves.
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.
Sonar navigation uses sound waves; radar navigation uses electromagnetic waves (usually radio eaves).
FM radio uses frequency modulation to broadcast sound over radio. FM radio waves are usually transmitted between 87.5 to 108.0 megahertz.
