What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
Can a red shift and a blue shift exist on the same object at the same time?
No, red shift and blue shift are opposite phenomena caused by the Doppler effect. Red shift occurs when an object is moving away from the observer, while blue shift occurs when an object is moving towards the observer. It is not possible for an object to exhibit both red shift and blue shift simultaneously.
What is an effect called in which a star or galaxy appears to move away from an observer?
red shift
What are the terms used to describe the effect on chromophore by auxochrome?
The effect of auxochrome on a chromophore is described by terms like bathochromic shift (red-shift), hypsochromic shift (blue-shift), and hyperchromic effect (increase in absorbance intensity). These terms refer to the changes in the absorption spectrum of a molecule due to the presence of an auxochrome group.
What is droppler effect?
The Doppler effect is the mix of red shift and blue shift. For example when your walking down the street and a car drives up from behind you and you don't see it but hear it your hearing the blue shift of the Doppler effect. also same scenario but the car has passed and driving away in front of you then your hearing the red shift of the Doppler effect. hope that helps I'm in 8th grade might wanna check but I'm pretty sure that's right well that's what we learned today anyway...:)
What causes a red shift?
When a light source is receding away from an observer then due to Doppler effect the frequency would appear to fall. Hence the colour would be shifted towards the red end. Hence red shift Same way as the source is apporaching the observer, then frequency would appear to increase and so it moves towards violet. Hence violet shift.

What creates the phenomeon known as red shift?
Two things can cause red-shift:- The rapid motion of an object away from the observer. This is known as the Doppler-effect.- Expansion of space between the object and the observer.
What does a distant galaxy having a greater red shift indicate about the universe?
A red-shift caused by the Doppler-effect indicates that the object is rapidly moving away from the observer.Note that at extreme distances, red-shift is not caused by the Doppler-effect, but primarily by the expansion of space between the object and the observer.
What is meant by red shift and what cause it?
Red shift is the phenomenon where light from an object in space appears to have a longer wavelength, shifting towards the red end of the spectrum. It is caused by the stretching of light waves due to the expansion of the universe, known as the Doppler effect.
Explain why some stars in the milky way galaxy have a blue shift Doppler effect and other stars in the milky way have a red shift Doppler?
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.
A red shift in the spectrum of the light from an object indicates the object is moving where?
A red shift in the spectrum of light from an object indicates that the object is moving away from the observer. This is a result of the Doppler effect, where the wavelengths of light are stretched as the object moves away, causing a shift towards the red end of the spectrum.
