Doppler effect, observed frequency

작성자 Uploader : physics 작성일 Upload Date: 2016-04-25변경일 Update Date: 2016-04-25조회수 View : 216

The Doppler effect (or the Doppler shift) is the change in frequency of a wave (or other periodic event) for an observer moving relative to its source.
In classical physics, where the speeds of source and the receiver relative to the medium are lower than the velocity of waves in the medium, the relationship between observed frequency f and emitted frequency f0 is given by:

f = f0*(c+vr)/(c+vs)
c : the velocity of waves in the medium (m/s)
vr : the velocity of the receiver relative to the medium (m/s)
   (positive : receiver is moving towards the source, negative : in the other direction)
vs : the velocity of the source relative to the medium (m/s)
   (positive : the source is moving away from the receiver, negative : in the other direction)
