What else can I help you with?
Which effect is employed in the instrument used by the police to defect the over speeding of vehicles?
Doppler effect
Which effect is employed in instrument used by police to detect over speeding of vehicle?
Doppler effect
How is the doopler effect used?
The Doppler effect is useful for and used for detecting objects velocity. The Doppler radar tells whether the object is heading toward or away from you or perpendicular to you.
Which one of the following effect is employed in the instrument sed by the police to detect the over speeding of vehicles?
The Doppler effect.
Is true of the Doppler effect?
the Doppler effect involves moving objectsthe Doppler effect involves moving objects
Do traffic lights use Doppler effect?
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.
Who was the Doppler Effect named after?
The Doppler Effect was named after Austrian physicist Christian Doppler, who first described it in 1842.
What did Christian Doppler do?
He discoverd the Doppler effect
Why big bang theory is presented?

What is the change in frequency of a sound due to motion of the source?
The change in frequency of a sound due to motion of the source is called the Doppler effect. If the source is moving towards the observer, the frequency of the sound appears higher (blueshifted), while if the source is moving away, the frequency appears lower (redshifted). This effect is commonly experienced with passing vehicles and sirens.
What does the Doppler Effect provide evidence for?
The Doppler effect proves that sound travels in waves.
What exactly is the Doppler effect?
The Doppler effect is the change in frequency of a sound wave. The Doppler effect causes a siren or engine to have a higher pitch when it is approaching than it does when it is receding.
