station as station 2 and as in the picture there are some horses on both the stations. When the train arrives on the station 2, the horses on it heard a louder sound. As the train passed away, the sound becomes fainter and fainter to those horses. Now the train is arriving on the station 1, then the horses on that station hears the same sound first fainter when the train was far away and then louder and louder as the train approaches them. This famous Effect was first studied by Christian Andreas Doppler and then formulated some famous principles.
