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.
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
What do you call an effect where in the pitch of the whistle rises as the train approaches the station and falls off as it moves away?
It is called the Doppler effect
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 is the Doppler effect and is it useful?
It is the effect that happens when waves like sound are moving in relation to another object. In the classic train whistle example, The whistle suddenly drops in pitch as it passes you and starts to move away from you. This is because the sound waves now are stretched out, giving them a lower pitch. It is useful. Doppler radar used in weather forecasting is one example.

The changing pitch of a police cars siren as it moves by you is an example of what?
The Doppler effect
What effect is red shift an example of?
The Doppler effect.
Why dont you notice the Doppler effect for a slow moving train?
The Doppler effect occurs whether the sound source or the listener is moving. You wont notice the Doppler effect on a slow moving train because the radio wave is reflected, its frequency changes depending on the speed of the object.
How is the Doppler effect on light waves analogous to the apparent change in pich of a passing train whistle?
When the train gets close to you the sound wave are compressed making a higher pitch noise and as the train passes the sound waves become lengthened. That is the doppler effect in a nutshell. Now just compare it to how the doppler effect changes light waves.
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
Why the tree near the train are seen running faster then distanced tree?
Doppler effect
Does the Doppler Effect mean that an observer ahead of a train hears the train at a higher frequency sound than an observer behind the train?
Yes that is the case.

Is true of the Doppler effect?
the Doppler effect involves moving objectsthe Doppler effect involves moving objects
