How does the Doppler effect aid police in detecting speeding motorists?
Step 1 of 3
The doppler effect is the change in frequency of a wave caused by relative motion of the wave emitter and receiver. The police radar unit sends out waves of invisible light at a specific frequency.some of the waves are bounces back from the vehicle and return back to the officer.the faster the relative motion larger the frequency shift.the radar unit calculates your speed and displays it on screen. Hence the doppler effect aid police in detecting speeding motorists.
