What is the comparison of the Doppler effect in electromagnetic radiation to the relativistic effect in electromagnetic radiation?

The Doppler effect is a real change to wavelength lambda when moving between media, or interacting with one or more particles of mass, caused both by different media motions (between wave peak arrivals) and different propagation speeds (refractive indices 'n'). It is detected via the 'observable' time based derivative 'frequency', (so often wrongly considered just as a 'frequency shift').
The 'Relativistic' effect is the imposition of a hyperbolic curve to 'prevent c+v' to try to explain why all detectors find c locally. Of course the Doppler effect gives local c/n in all media anyway because c = f*lambda is a constant. The effect was proposed before we knew that space was a diffuse medium itself, the Interstellar or Intergalactic medium (ISM - IGM) or the 'quantum vacuum', or 'Higgs Field', but will remain mainstream theory until a more consistent complete replacement is adopted.

What are the properties of electromagnetic waves and interactions that make Doppler radar possible?
Doppler radar wouldn't be possible if the speed of light were infinite. Also it wouldn't be possible if the electromagnetic waves didn't reflect on objects. Also it helps a lot if those electromagnetic waves have a particular frequency as opposed to a wide spectrum. --Some person named Adrian who did the research
The Doppler shifting of radiation from the early universe has resulted in today's universe being bathed in a sea of?
Cosmic Microwave Background (CMB) Radiation.
What is the violet shift?
a decrease in the wavelength of radiation emitted by a celestial body as a consequence of the doppler effect
What are the health issues living near a Doppler radar?
Radiation exposure is a serious problem for residents in close proximity to a radar or microwave transmitting antenna.
Do gamma rays have the longest wavelength?
Gamma rays are electromagnetic radiation just like visible light, X-rays, heat, and radio waves. The wavelength that you experience depends on how fast you and the source are moving together or apart. This is the Doppler-shift. So if you travel just in front of a glowing red-hot rock, keeping the same distance, the radiation will be infra-red. If, however, you are far away, and for some reason the rock and you are getting close together very fast, then the wavelength to you, as that particular observer will squash up dramatically and the radiation will have moved into a more energetic higher-frequency form, perhaps beyond visible light, into ultra violate and further. Apart from this Doppler shift, quantum effects at the source of the radiation govern its initial frequency where higher energy transitions produce more energetic, and shorter wavelengths. An exploding star is likely to create a lot of high energy, short wavelength gamma radiation, whereas a volcanic eruption would produce long wave heat radiation. So the answer is : "This cannot be answered." You would have to ask the question compared to an energy and motion bound. In any case, gamma rays are particularly energetic and are generally considered very short wavelengths compared to the other observable radiation in the universe.
The increase in frequency of an approaching source of electromagnetic radiation is termed the?
Doppler effect
Is the Doppler effect is the same as sound waves?
I fear you're confused - BUT : The Doppler effect is similar for both sound waves and electromagnetic radiation (light, radar).
Can Doppler's Effect only be observed in sound waves?
No. We observe the Doppler Effect in all forms of waves, including sound waves and all forms of electromagnetic radiation.

What has the electromagnetic spectrum got to do with the Doppler Effect?
The Doppler effect affects any wave, including electromagnetic waves. Basically, the idea of the Doppler effect is that the frequency of a wave increases when an object approaches you, and it decreases when it moves away from you. You can imagine that the sound waves, or electromagnetic waves, become compressed when the emitting object moves toward you.
What term describe an apparent change in frequency of sound waves of rapidly moving?
Doppler Shift. It occurs in electromagnetic radiation too, though is really only significant at extremely high speeds such as the recession-rate of galaxies.
What has the author Wallace Kantor written?
Wallace Kantor has written: 'Relativistic propagation of light' -- subject(s): Light, Measurement, Speed, Relativity (Physics), Doppler effect
The Doppler shifting of radiation from the early universe has resulted in today's universe being bathed in a sea of?
Cosmic Microwave Background (CMB) Radiation.
What is a C-Band Doppler radar?
C-Band Doppler Radar is any Doppler radar system which operates in the C-Band of the electromagnetic spectrum (around 4.8Ghz). These are typically the radar systems seen at TV stations as they are affordable and powerful enough for their purposes.
What is the Doppler effect and how does it alter the way you perceive radiation?
watch the bing bang theory on 2
What is the violet shift?
a decrease in the wavelength of radiation emitted by a celestial body as a consequence of the doppler effect
What scientists use to support the big bang theory?
The Doppler effect and background cosmic radiation are the big ones.
