How do you finish rearranging the Doppler shift formula

  1. Jan 24, 2013 #1
    1. The problem statement, all variables and given/known data

    i am using the Doppler shift formula Fs=F0(1/1+-(vsource/c) i can rearrange it to an extent but when i use it to find my answer i i need to divide it by two in order to do it, every time. I would just like to understand why this is, or if i am doing it completely wrong.


    3. The attempt at a solution
    ((Fs/F0)-1)*V(sound)=Vsource
    but if i turn it into 2Vsource it comes out that i will get the right answer when i divide it by two to get vsource, so please explain why there is a two there.

    Please and thank you for your help.

    If I understand your symbols, I think you've got the ratio of the frequencies upside down.

    Yes, thank you, they were reversed, that created my formula to be positive instead of a negative end number, but i still need to divide Vsource by 2 in order to get the correct answer.
