The star is moving away from us. Therefore, the Doppler effect must be considered. The Doppler effect is waves (in this case light) will be compressed in front of a moving object and stretched behind the object. This stretching creates a long wavelength. Red light has a long wavelength (the longest of visible light), so we call this stretching red shift.
No. A red shift indicates that the object is moving away from the earth.
a star is moving AWAY FROM EARTH
Yes. If the star is moving away from the Earth, its spectral lines will shift towards the red end of the spectrum. If it is moving towards the Earth, its spectral lines will shift towards the violet end of the spectrum. This is due to Doppler effect.
The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
Red shift occurs when an object moves away from the observer. So as you are on Earth, it is when objects move away from Earth. (Blue shift as it moves closer.) A star's red shift could be due to losing energy to gravity.
When stars or galaxies are moving away from the observer, you will notice a redder shift in the color of the body.
Since the stars are not stationary in relation to earth, i.e. they are moving towards or away from the Earth, their light will be subject to Redshift (if they are moving away) or Blueshift (if they are getting closer). The faster they are changing distance, the greater the shift in wavelength.
No. A red shift indicates that the object is moving away from the earth.
Doppler shift
a star is moving AWAY FROM EARTH
Distant stars appear red shifted because they are travelling away from Earth. It just happens that more distant stars are moving faster, so there is a greater red-shift the further a star is from the Earth.
It is called The Doppler Shift
Yes. If the star is moving away from the Earth, its spectral lines will shift towards the red end of the spectrum. If it is moving towards the Earth, its spectral lines will shift towards the violet end of the spectrum. This is due to Doppler effect.
The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
Different sized stars burn at different temperatures. Different temperatures produce different colours. Stars that are moving away from us will shift their colours towards the red. This is called "Red shift".
Red shift occurs when an object moves away from the observer. So as you are on Earth, it is when objects move away from Earth. (Blue shift as it moves closer.) A star's red shift could be due to losing energy to gravity.
A blue-shift means an object is moving towards us, a red-shift means it is moving away from us. Blue-shift and red-shift are changes in frequency of the light we receive, due to the relative movement. This is called the Doppler effect.
