When an object moves away from us, or towards us.
A blue shift is observed in the spectrum from an object approaching the observer whereas a red shift is observed for a receding object.
Christian Doppler, an Austrian physicist, is credited with discovering the phenomenon of the Doppler red shift in 1842. He observed that the pitch of sound waves from a moving object changes depending on the object's motion relative to the observer. His theory was later extended to light waves to explain the red shift observed in the spectra of distant galaxies.
The light waves are redshifted, meaning their wavelengths increase and their frequencies decrease. This effect is due to the Doppler effect, where the motion of the object causes a shift in the observed wavelength of light.
Betelgeuse is a red supergiant star located in the Orion constellation. Its light exhibits a small Doppler shift due to its motion relative to Earth, but this shift is not significant compared to its overall distance and size. The Doppler shift of Betelgeuse's light is mainly influenced by its own pulsations and variations in brightness.
Doppler shift shows that galaxies are moving away from each other at rates that depend on how far apart they are. According to the Big Bang Theory, the universe began with an enormous explosion. Then, the entire universe began to expand everywhere at the same time.The doppler shift shows that galaxies are moving away from each other at rates that depend on how far apart they are.

The Doppler shift is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the source of the wave. When the observer is moving towards the source, the frequency appears higher (blue shift), and when moving away, the frequency appears lower (red shift). This effect is commonly observed in everyday situations, such as the change in pitch of a siren as a police car passes by.
What shifts is the frequencies of the light. This can be observed by certain lines in the spectrum, which have very specific positions (frequencies).
The light waves are redshifted, meaning their wavelengths increase and their frequencies decrease. This effect is due to the Doppler effect, where the motion of the object causes a shift in the observed wavelength of light.
The Doppler effect can be observed with both longitudinal waves (such as sound waves) and transverse waves (such as light waves). The effect causes a shift in frequency due to relative motion between the source of the wave and the observer.
Doppler shift is the change in frequency of a wave that seems to occur as it moves. Scientists study the doppler shift to see whether stars are moving away from or toward our galaxy.
Yes, light waves show the Doppler effect. This is commonly observed as a shift in the wavelength of light from a moving source, similar to the change in pitch of a siren as it approaches and then moves away from an observer.
Doppler shift
The amount of Doppler shift depends on speed - the faster vehicle will show more Doppler shift.
A Doppler red-shift is a shift in recognizable features of a star's spectrum from the wavelengths where we know they belong toward longer wavelengths. Such a shift can be caused by the star's moving away from us, and that's how it's interpreted when astronomers see it. A Doppler blue-shift is a shift in recognizable features of a star's spectrum from the wavelengths where we know they belong toward shorter wavelengths. Such a shift can be caused by the star's moving toward us, and that's how it's interpreted when astronomers see it.
