Doppler Effect Approaching Source Calculation

This is a useful online Doppler effect approaching source calculator which works based on the formula of Doppler effect to calculate the new frequency of approaching source. Doppler effect is the effect of a change in sound variations between a distant and approaching source and the moving or still receiver. In the below calculator enter the values for wave velocity and wavelength in front of a source to perform Doppler effect approaching source calculation.

The Doppler Effect was named after the Austrian Physicist Christian Doppler, who proposed this effect in 1842 in Prague. Doppler shift is the change of pitch of the sound heard when a vehicle sounding a siren or horn approaches, passes and recedes from an observer. The doppler effect approaching source calculation is important in analysing Doppler shift.
