As far as I know, there will always be a Doppler effect when there is relative movement between the object that emits sound, and the observer (i.e. you, who are listening to the sound).

What conditions would you have to be met in order for an ambulance with its siren on not exhibit the Doppler effect when it passes you?

It would have to move very, very slowly.


Why does a paramedic in an ambulance doesn't experience the Doppler effect the siren?

If the ambulance was moving either towards you or away from you it would exhibit the Doppler effect.I.E. Higher pitch if it was moving towards you and lower pitch if it was moving away from you.The change is most noticeable if the vehicle passes you. Presumably more noticeable with lower frequencies than higher frequencies.


What is the name of the effect the causes the pitch of an ambulance siren to change as it passes you?

The Doppler effect


What type of waves exhibit the Doppler effect?

All types of waves exhibit the Doppler effect, including sound waves, light waves, and water waves. The Doppler effect is the apparent change in frequency of a wave caused by the relative motion between the source of the wave and the observer.


How do you use doppler in a sentence?

My doctor uses a doppler to amplify the baby's heartbeat.


As you drive down the road you see and hear an approaching ambulance How is the frequency you hear different from that being produced by the ambulance?

The wavelengths of the sound are compressed, making them shorter, and thus the frequency (and the pitch) higher. So the person in the oncoming car hears the siren operating at a higher pitch than the ambulance driver hears the same siren. This phenomenon is known as the Doppler effect.


Is true of the Doppler effect?

the Doppler effect involves moving objectsthe Doppler effect involves moving objects


How can a person observe the Doppler effect?

A person can observe the Doppler effect by noticing changes in the pitch of sound as a source of sound moves relative to the observer. For example, an ambulance siren sounds higher pitched as it approaches and lower pitched as it moves away. In astronomy, the Doppler effect causes shifts in the color of light from stars as they move towards or away from Earth.


Where can you find a Doppler effect?

you can find a Doppler effect when a police car passes by you, or a train, or a fire truck, or anything mobile that makes noise. one is usually more noticeable when the mobile object emits a louder noise. the Doppler effect is the apparent decrease in sound frequency.

The velocity of sound in air is 343 ms An ambulance is traveling east at 64.9 ms Behind it there is a car traveling along the same direction at 29.8 ms The ambulance driver hears his siren at a?

afrequency of the same as siren frequency as ambulance is the source and the observer this is not Doppler effect problem


Who was the Doppler Effect named after?

The Doppler Effect was named after Austrian physicist Christian Doppler, who first described it in 1842.
