Why doesn't the Doppler shift appear when an observer moves toward the source?
Doppler's effect does not happen when the observer is moving towards the source because unlike the source when observer moves forward the waves are not compressed and they pass the observer without being compressed and since the doppler effect is due to the Change in wavelength of the wave, it fails to occur.
Is it possible to move a source of sound relative to a stationary observer so that there is no shift in the frequency of the sound?
For the sound from a source not to be shift in frequency , the radial velocity of the source to the observer must be zero : that is the source must not be moving towards or away from the observer
How does the frequency measured in front of the source appear to the observer compared to the frequency measured from behind?
The frequencies are the same, unless the source is moving relative to the observer.
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.
What is the redshift star?
The redshift is caused by relative motion that increases the distance from the source to the observer. The faster the source of light is moving away to the observer, the greater the redshift
What does nadir mean?
Answer1. an extreme state of adversity; lowest point of anything2. the point below the observer that is directly opposite the zenith on the imaginary sphere against which celestial bodies appear to be projected
What part of speech is observer?
"Observer" is a noun.
What is the best constructed cathedral made by Medieval Stone Masons?
The answer depends very much on your understanding of "best constructed". Does this mean the best looking? The best decorated? The tallest? The largest ground plan? The best foundations? The best structural integrity? The most stable? The least rebuilt?"Best" is always an impossible term to quantify; every observer will have a different opinion about which medieval cathedral is best constructed - and there are hundreds across Europe that could reasonably hold the title.
What is an azimuth and elevation?
These are terms used in surveying and astronomy (usually quotes in angles) to denote the apparent position of an object in the sky based on a specific obervation point or an observer on the Earth's surface.
