No. If you're driving fast enough to cause a noticeable Doppler shift in the apparent
color of the traffic lights, then you have several speeding tickets coming for sure, no
questions asked.
Example sentence - We are learning to what the doppler effect is and how to use it.
The Doppler effect allows us to use the spectrum to study a source's motion. This effect causes a shift in the wavelengths of light emitted by a moving source, which can be detected and used to determine the direction and speed of the source's motion relative to the observer.
My doctor uses a doppler to amplify the baby's heartbeat.
Yes, police officers can use their lights to navigate through traffic in emergency situations or when responding to a call.
Christian Doppler discovered the Doppler effect in 1842. He observed that the frequency of sound changes as the object of the sounds moves and the detector of the sound moves. Radar and medical devices use the Doppler effect to locate and provide images of scanned objects.

Traffic signals use photoelectric sensors to detect the presence of vehicles at intersections. These sensors emit a beam of light, and when a vehicle passes through the beam, it blocks the light, triggering the signal to change. This system enables traffic signals to efficiently control the flow of traffic at junctions.
Meteorologists use the Doppler effect in weather forecasts by analyzing how the frequency of radar waves is altered when they interact with precipitation particles. By measuring the change in frequency, meteorologists can determine the speed and direction of winds associated with storms, as well as the intensity and movement of precipitation. This information helps in predicting the development and movement of weather systems with greater accuracy.
The Doppler effect and background cosmic radiation are the big ones.
