It would have to move very, very slowly.
no
Doppler effect Red Shift
The most plausible explanation for the redshift is that galaxies are moving away from us. This is similar to the Doppler effect, but it is normally believed that space itself is expanding, so the situation is a bit different from the "normal" Doppler effect.
How close and far something is from you.
The red shift IS the Doppler Effect. I use the sound of a car or motor bike passing by on a road. The high pitch of the approaching vehicle suddenly drops to a low pitch as it speeds by and retreats.Note:Cosmological redshift is not attributed to the Doppler Effect, but to the metric expansion of the universe.
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).
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.
The Doppler effect
i was taught that it is what an ambulance does when it goes past
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.
The change in frequency is caused by the Doppler Effect
the Doppler effect involves moving objectsthe Doppler effect involves moving objects
He discoverd the Doppler effect
The Doppler effect.The Doppler effect.The Doppler effect.The Doppler effect.
afrequency of the same as siren frequency as ambulance is the source and the observer this is not Doppler effect problem
It is quite clear, from the Doppler effect, that the Universe is expanding.It is quite clear, from the Doppler effect, that the Universe is expanding.It is quite clear, from the Doppler effect, that the Universe is expanding.It is quite clear, from the Doppler effect, that the Universe is expanding.
The Doppler effect proves that sound travels in waves.
