Ultrasound diathermy employs high-frequency acoustic vibrations which when propelled through the tissues are converted to heat. It is generally used to deliver heat to selected structures because there is a difference in the sensitivity of various fibers to the acoustic vibrations.

Frequency is the number of occurences of a repeating event per unit time
Frequency is how many waves pass a certain point during an amount of time. Wavelength is the distance between two points. Frequency and wavelength are inversely proportional in Physics. If the distance between the peaks of a wave decreases, the frequency of the wave increases. If the distance is increased, the frequency decreases.
Increasing a wave's wavelength will most certainly decrease its frequency. See Physics.

The higher the frequency the shorter the wavelength, so by the physics of sound waves, the smaller the objects that can reflect the sound back. Hence using ultrasound, with its very short wavelengths, the better the definition attainable.

Acoustics is the study of sound, ultrasound and infrasound, that is, waves in gases, liquids, and solids.
RF is used as an abbreviation of "radio frequency".
Tightening a string changes the fundamental frequency and affects the frequencies of all subsequent harmonics. That's the physics definition. In reality, tightening a string will make its pitch higher (increasing frequency) and keeping strings tightened to where they're supposed to be ensures that it makes the sounds its supposed to make.
