Do you have a schematic for a Wien bridge oscillator? Do you know a formula for the frequency?

Could you please solve me this question?

Design a Wien bridge circuit to oscillate at 500kHz
And how will you learn anything if we do the work for you?

Did a google search of "Wein bridge oscillator" recognized the author was academic then I used an online RC calculator.
The video shows Wien Bridge design. Then roughly from calculator ( high and low pass R=160Ω, C=2nF might work for 500kHz)
Scope of sine output, the redrawn circuit, the math work shown at starting about 15:00. Good project, I believe it can be done
without reviewing a million web pages but getting started is half finishing.
