Is Bluetooth radio frequency?

Physical range: Typically less than 10 m (33 ft),

Keeping this in consideration, is Bluetooth considered RF?

Yes. Bluetooth is one of the low power wireless transmission technology. It uses RF signals to transmit and receive. It has been designed under the specification of IEEE 802.15.

One may also ask, does Bluetooth use 2.4 GHz? The Problem. To communicate between your devices, Bluetooth sends signals over a 2.4GHz radio frequency. What's more, most of today's Bluetooth technology use what's called spread-spectrum frequency hopping. That is, they rotate between 70 randomly chose frequencies within their range, changing 1,600 times a second.

Beside this, what is the difference between Bluetooth and radio frequency?

Bluetooth technology runs on 2.4GHz RF. Most Bluetooth headsets run with Class 2 Bluetooth, which provides a range of up to 33 feet. Other RF wireless headsets run on different frequencies, from 900MHz to 3.2GHz.
