    What is the equation for doppler effect?

    What is the speed of the generator when the professor is twirling it? suppose the students are gathered at together right in front of the professor...

    In the circular path of the generator when is the generator moving fastest towards the students... this gives the maximum frequency... when does it move fastest away from the students... this gives the minimum frequency.
