The frequency is given by 1/2piRC, where R is 10.5k is this circuits and C is 0.015uF. The oscillations are generates by a specific gain of the op-amp, that is the same as the losses in the wein bridge circuit. The gain is typically of 3, but we have to put some compensation in the feedback to be sure that the oscillations doesn't stop. I think that here it's the 2 diode's, but it's the first time I say something like that. Most of the time it's a J-Fet that make the job.
