Red shift is of virtually no importance in determining the age of stars within our galaxy or local group. But the red shift is crucial for measuring relative velocities of those stars with respect to us. Stars approaching us are blue shifted, such as the stars in the Andromeda Galaxy. We can also determine which direction the galaxy is spinning, as the light of stars one one side will be shifted less than the light of the stars in front, or on the other side.

Starlight from galaxies well beyond our local group are uniformly shifted towards the infrared end of the visible spectrum, varying with the distance of those galaxies from us. The further away they are, the deeper red the light is from them, indicating the greater their recessional velocity.

I cannot think how stellar age might correlate with red shift.

A red Doppler shift indicates that a star is moving .?

A red Doppler shift indicates that a star is moving away from the observer. This phenomenon occurs because the wavelengths of light emitted by the star are stretched as it recedes, making them appear redder. In contrast, a blue Doppler shift would indicate that the star is moving toward the observer. This shift is a critical tool in astrophysics for determining the motion of celestial objects.


Where is Betelgeuse on Doppler Shift?

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.


When light waves are stretched by an object moving away from us?

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.


If we saw a galaxy's light had blue shifted what does that tell us about it's motion?

If a galaxy's light is blue-shifted, it indicates that the galaxy is moving toward us. This shift occurs because the wavelengths of light are compressed as the source approaches, resulting in a shift toward the blue end of the spectrum. This phenomenon is a key piece of evidence for the motion of celestial objects and can help astronomers determine their velocities relative to Earth.


The Doppler shift can be observed when?

The Doppler shift can be observed when there is relative motion between a source of waves (such as sound or light) and an observer. This causes a change in the frequency of the waves detected by the observer, either increasing or decreasing depending on the direction of motion.

When do we experience the Doppler shift?

We experience the Doppler shift when there is relative motion between a source of waves (such as sound or light) and an observer. This shift causes a change in frequency or wavelength of the waves depending on the direction of their motion relative to each other. doppler shift is commonly noticed in scenarios like the change in pitch of a siren as it passes by or the color shift of stars due to their motion in space.

What kind of shift would you see if a light was moving away from you?

You would observe a redshift in the light as it moves away from you. This occurs because the wavelengths of light are stretched due to the motion of the source away from the observer, causing a shift towards the red end of the spectrum.

How does the speed of a wave affect its wavelength?

This can be answered using light or sound. Light will remain at a constant speed regardless of frequency or amplitude. Its shift in frequency (Doppler shift) is caused by the extreme distances the light had to travel to get here. Still it remains at the same speed. Sounds speed will change with local conditions. Also subject to an audible Doppler shift when a constant note is moved past you you can hear the pitch shift. The motion compresses the sound as it approaches and spreads it out as it moves away from you.
