Doppler effect generally is the change in frequency of a wave( majorly sound wave) for an observer moving relative to the source of the wave.
f=[(v+vr)/(v+vs)]f0
where is the velocity of waves in the medium is the velocity of the receiver relative to the medium; positive if the receiver is moving towards the source. is the velocity of the source relative to the medium; positive if the source is moving away from the receiver.

How do you briefly explain the Doppler effect?
By keeping the explanation short.
What is the change in frequency of a sound due to motion of the source?
The change in frequency is caused by the Doppler Effect
Is true of the Doppler effect?
the Doppler effect involves moving objectsthe Doppler effect involves moving objects
Does the Doppler Effect explain why you hear a train whistle differently after it passes you than you do as it approaches you?
Yes (True)
What did Christian Doppler do?
He discoverd the Doppler effect
A detected apparent change in the pitch caused by the motion of a sound source or of an observer is called?
The Doppler effect.The Doppler effect.The Doppler effect.The Doppler effect.
Why big bang theory is presented?

What does the Doppler Effect provide evidence for?
The Doppler effect proves that sound travels in waves.
How can you use Doppler effect in a sentence?
Example sentence - We are learning to what the doppler effect is and how to use it.
Who discovered the Doppler effect?
Christian Doppler did not invent Doppler Radar. He described what is now known as the Doppler effect in 1842 in Austria. It is used to describe the behavior of waves (such as light or sound) that are emitted by a moving object. Doppler radar, which utilizes the Doppler effect, was developed in the United States during World War II.
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.
What is an explanation of the Doppler shift?
The Doppler Shift is a change in frequency due to the Doppler Effect.
