Chapter 4.5/A2 The Doppler Effect Thursday, January 24, 2013 6:20 PM ? Formulas & Theorems Covered Today: Frequency Formula Moving Source Toward: Fo= Fs/ 1- (vs /c) Away: Fo= Fs/ 1+ (vs /c) Moving Observer Toward: Fo= Fs* [1+ (vo /c)] Away: Fo= Fs* [1- (vo /c)] Wavelength Formula Moving Source ?o = ?s (1 - (vs/c)) Moving Observer Example Questions: Sound wave f= 300Hz is emitted towards approaching car (moving observer towards). Wave is reflected back f2= 315Hz (moving source towards). V of the car? ? ? v= 8.29 m/s ? A train with siren of 500Hz is moving at a constant speed of 8.0 m/s. What f does observer hear? ? Calculate the train f moving towards and away and that is the range of frequency that the observer will hear. ?
