Suppose a person is travelling towards a wall with a tuning fork at frequency 'f' at a speed of 'v*'. Using the doppler effect equation:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] f' \ = \frac{v + v_o}{v - v_s} [/tex]

What would the sign of v_o and v_s be? I don't understand, since the man is both the observer and the source. (Let - be receeding and + be approaching).
