Candidate of physico-mathematical Sciences Yury Goryunov successfully challenged the penalty of traffic police, after analyzing the prosecution in his address from the point of view of the laws of physics. To win a court scholar and lecturer from Kazan helped the Doppler effect.

In August last year, mobile photoradar recorded that the car of Yury Goryunov Kazan on one of the roads exceeded the maximum permissible speed, comprising 70 kilometers per hour. The readings point to the fact that the physicist in his car clocked up 92 miles per hour, and a month later he came to a fine of 500 rubles, writes the local newspaper “Evening Kazan”.
The scientist, in turn, the penalty refused to pay, arguing that the speedometer of his car showed no more than 80 kilometers per hour throughout the road. His innocence physicist decided to prove in court. Further, by studying the images that was attached to the letter of the traffic police, Goryunov noticed that the sensor of the red light camera is located below the bottom of his car. This allowed scientist to declare that because of the Doppler effect the wave propagation in this case should decrease, causing radioradar and could give incorrect results. Goryunov also suggested that the sensor could be installed incorrectly.
The Doppler effect, named after its discoverer, Australian Christian Doppler, is the change in frequency and wavelength perceived by the receiver due to motion of the radiation source or the observer. This phenomenon often allows scientists to achieve significantly less “applied” purposes than avoidance of a relatively small fine. For example, it is thanks to the Doppler effect American experts managed with a high degree of reliability to determine the expected point of fall of the fragments of the three-meter meteor spotted last night over Arizona.Related posts:
