Question

Doppler effect formula

Answer 1

The simplest way to experience the Doppler effect is to stand nearby a road or railroad and listen to how the sounds change. Fir this scenario, the Doppler effect formula is

$$f=\frac{c}{c-v_s}f_0,$$

where

f₀ - original frequency of the source,

c - speed of sound/light

v_s - speed of the source moving toward the observer.
