Doppler Effect Calculator
Use this calculator to find the observed frequency of a sound wave when either the source or the observer (or both) are in motion. Applies the classical Doppler Effect for sound.
What this calculator is doing
The Doppler Effect describes the change in frequency (or wavelength) of a wave in relation to an observer moving relative to the source of the wave.
For sound, the observed frequency \( f' \) is calculated using:
\[ f' = f \cdot \frac{v + v_o}{v - v_s} \]
Where:
\( f' \) = Observed frequency (Hz)
\( f \) = Source frequency (Hz)
\( v \) = Speed of sound in the medium (typically 343 m/s in air)
\( v_o \) = Observer speed (positive if moving toward the source)
\( v_s \) = Source speed (positive if moving toward the observer)
The equation assumes all motion is along the line connecting the source and observer.
