What else can I help you with?
If an object is moving away from you and left alone what happens?
If an object is moving away from you and there are no forces acting on it,then it continues moving in a straight line at constant speed.
What indicate redshifting to astronomers?
The object is moving away from the observer.
When the wavelength of a spectral line emitted from an object increases which end of the visible light spectrum does not move toward and what is the objects motion relative to earth?
Increasing wavelength is an indication of a Doppler shift caused by an object moving away from the viewer. Longer wavelengths (of the visible spectrum) are redder, shorter wavelengths are bluer. Objects moving away from you have a red shift, objects moving toward you have a blue shift.
Why is the Andromeda galaxy moving toward earth?
Sorry, Andromeda and earth are moving away from each other, not towards each other.
What does it mean when the color of an object in the universe shifts toward red?
When the color of an object in the universe shifts towards red, it indicates that the object is moving away from the observer. This phenomenon, known as redshift, is caused by the expansion of the universe and the stretching of light waves as they travel through expanding space.
Does a red shift means that are moving closer to earth?
No. A red shift indicates that the object is moving away from the earth.
Does a red shift indicates that objects are moving toward earth?
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.
What does red shift show?
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.
A Doppler red shift indicates?
that an object is moving away from an observer. This red shift occurs because the wavelength of light is stretched as the object moves farther away, causing it to appear more red. This effect is commonly seen in astronomy with galaxies moving away from us due to the expansion of the universe.
How can an object's red shift tell us how fast the object is moving away from earth?
The amount of reddening is directly proportional to the speed of the object away from the observer (if the object is moving tangentially, even at a high speed, no red shift will be noticeable. Follow the link below for a bit more information on the mathematics and measurements of red shifts.
If an object is moving away from you and left alone what happens?
If an object is moving away from you and there are no forces acting on it,then it continues moving in a straight line at constant speed.
Would a light source moving away from Earth appear blue shifted or red shifted?
A red shift indicates an object that is moving away from the observer, and a blue shift indicates an object that is moving toward the observer. Both of these are called Doppler shifts.
Is it true that the farther away from Earth a galaxy is the slower it is moving?
incorrect. The farther away from earth a galaxy is, the faster it is moving.
Is the moon moving closer to the Earth or farther away?
The moon is moving further away by 1.5cm from the Earth every year.
What is the frequency in a sound wave created by a moving object?
The frequency of a sound wave created by a moving object will increase if the object is moving towards the observer and decrease if the object is moving away. This effect is known as the Doppler effect.
A red shift in the spectrum of the light from an object indicates the object is?
moving away from us.
How can astronomers determine whether a star is moving towards or away from earth?
Astronomers determine whether a star is moving toward or away from the Earth via the Doppler effect. Imagine a motorcycle moving past you. As it drives towards you, it has a higher frequency, and a lower frequency when it drives away. The same thing happens with light. As an object moves towards us, its light has a higher frequency and lower wavelength - this is called blueshift. As an object moves away from us, its light has a lower frequency and higher wavelength - this is called redshift.
