What is blue shift?
Blue shift is a phenomenon whereby a moving object emits light in such a way that the waves of light actually posses a higher frequency than when emitted. Its like a pitcher throwing a fastball versus the same pitcher throwing a fastball from a moving vehicle; to an observer on the side of the road, the ball has a higher velocity when being thrown from the vehicle than from a stationary pitcher. The higher frequency of the light results in a shift towards the blue-end of the visible light spectrum; hence the name blue shift. This is a method used in astronomy to determine that a visible object is moving towards the Earth.
What shift of color do you receive from stars as you get closer?
Blue shift as you get closer because by the Doppler effect, the frequency of the light increases, so the light seems more blue. Using the same logic, there is a red shift for light as you move away from stars.
What type of shift in the spectrum would you expect from a star that was moving in the same direction as earth at the same speed of earth?
You would expect no shift in its spectrum. Any shift one way or the other is the result ofmotion either toward or away from Earth. Motion parallel to ours or across our line of sighthas no effect on the observed spectrum of the object.
How do you calculate red shift?
The spectrum of light emitted from heated hydrogen has dark lines, caused by the absorption of a very narrow wavelength band of light. These dark lines always take the same location relative to each other. If all the lines in an object's spectrum are shifted by the same amount, towards the red end of the visible spectrum, then the light is "red shifted." The amount of the shift is often described with a number 'z', where z equals the shift in wavelength divided by the wavelength as originally emitted by the object.
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.
Can red shift and blue shift exist on the same object at the same time?
Yes, if the object is spinning there will be red shifts on the half moving away and blue shifts on the half moving closer.This is one way tornadoes are detected using Doppler RADAR, the water droplets on one side of the cloud are moving away (red shift) while those on the other side are moving closer (blue shift), showing that the cloud is rotating.Solid spinning objects act the same and the rotation is detectable with Doppler RADAR.

Can there be purple shift aswell as blue shift and red shift?
Redshift and blueshift refer to a change in frequency of light we receive from distant objects (stars, galaxies, etc.) The light can turn different colors, and purple is one of them. However, no matter what the color the light changes to, the technical term is always "redshift" if the frequency of the light decreases (normally indicating that the object is moving away from us), and "blueshift" if it increases (normally indicating that the object is moving towards us). Blue shift and purple shift would mean the same thing because the spectrum is one-dimensional. It's like if you are in Boston, a shift towards Chicago is the same as a shift towards San Francisco. Obviously, a purple shift is a super blue shift.
When lateral shift is zero?
When the lateral shift is zero, it means that there is no horizontal displacement of an object or point from its original position. This indicates that the object or point remains aligned along the same vertical axis.
What happens when a juggernaut meets an immovable object?
It is impossible for a juggernaut and an immovable object to exist in the same universe and dimension.
How far the object from the center when shifted lpo to hpo?
The distance of the object from the center increases by the same amount as the shift from low to high point.
What shift of color do you receive from stars as you get closer?
Blue shift as you get closer because by the Doppler effect, the frequency of the light increases, so the light seems more blue. Using the same logic, there is a red shift for light as you move away from stars.
Can a blue object absorb the color blue and refracts all other colors?
No, a blue object absorbs most colors except blue, which it reflects. It does not refract colors in the same way that a prism or water droplet does.
Is there any cheats for superstar racing?
Yes there are ... you see when you pres shift+6 and shift+r u can whrite red letters its the same with blue u just go shift+b :)
What density of the blue object is true?
The density of the blue object is determined by dividing the mass of the object by its volume. It is a measure of how much mass is contained in a given volume. The formula for density is density = mass/volume.
How can two different opbjects with different speeds give off the same red shift?
No one ever said that they do. In fact, the only way we know a distant object's [radial] speed is through its red shift. So if two objects have the same red shift, then as far as anybody knows, they have the same speed.
How are blue shift and red shift the same?
Light received by an observer is affected if the observer or the source are moving towards or away from one another. This is the Doppler Effect.This is sort of like a race car.As it's approaching you, its noise sounds higher in pitch, and lower in pitch as it's moving away from you.Light waves - just like sound waves - are affected by relative movement between the observer and source.When the observer is moving away from the light source, the light is shifted to the red end of the light spectrum. The light waves are "stretched". There is further between the peaks of the wave.So, the wavelength increases. That means a shift from blue to red in the spectrum.By convention, the shift towards longer wavelengths is called a redshift.In fact, red light could be shifted to infrared."Redshift" just means a change in the observed light towards longer wavelengths.When the observer is moving towards the light source, th light shifts to the blue end of the light spectrum. We call that a blueshift.Redshifts can also be caused by the effect of gravity.Answer2:Redshift by gravity is F =mGM/r2= vp/rvp/r=vp/ct=(v/c)p/t = (v/c)mv/t = (v/c)ma.Gravity creates the velocity v and v/c is the "redshift" due to gravity v and not due to universe expansion of the recession of the body. The redshift of the earth is v/c = 30k/300M = 1/10k.
