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.
What does a red shift in the spectrum of light from an object indicate?
The visible spectrum contains two ends, infrared and ultraviolet. A shift of light towards the infrared end typically indicates the object is receding from the observer. Another explanation is that the object may be entering a deep gravity well, which would also stretch and distort light reflected or emitted from the object.
What does a blue and red shift of absorption lines in a spectrum indicate?
Blue shift is a decrease of a signal's wavelength, and/or an increase in its frequency, due to the Doppler Effect. This indicates that the object is moving towards the observer.Red shift is the increase of a signal's wavelength, and/or a decrease in its frequency, due to the Doppler Effect. This indicates that the object is moving away from the observer.
What does a red shift in the spectrum of light from an object indicate about the object?
Usually, that the object is moving away from us. It may also mean that the light comes from a "gravitational well", that is, that the light has to escape from gravity before it reaches us - this will make the light lose some energy, and shift towards the red part of the spectrum.
What does a blue shift in the spectrum indicate?
A blue shift in the spectrum indicates that an object is moving toward the observer, resulting in a decrease in the wavelength of the emitted light. This phenomenon is often observed in astronomy, where it can signify that a star or galaxy is approaching Earth. The shift towards the blue end of the spectrum occurs due to the Doppler effect, which affects the frequency of waves as the source moves relative to an observer.

What does the blue shift in the spectrum of light from an object indicate the object is moving?
A blue shift in the spectrum of light from an object would indicate that the object is moving towards the observer. The blue shift indicates that the object is under centripetal force. The object may not be moving toward the center if it is balanced by centrifugal force (repulsion) from the center.
What does a red shift in the spectrum of light from an object indicate about the object?
Usually, that the object is moving away from us. It may also mean that the light comes from a "gravitational well", that is, that the light has to escape from gravity before it reaches us - this will make the light lose some energy, and shift towards the red part of the spectrum.
Which end of the spectrum does light from an object move to when it moves away from an observer?
As an object moves away from an observer, the light from the object shifts towards the red end of the spectrum. This is known as redshift, and it occurs because the motion of the object causes the light waves to stretch out, which leads to longer wavelengths and a shift towards the red end of the spectrum.
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 a red shift tell astronomers about the movement of an object?
A red shift indicates that an object is moving away from the observer. This is a result of the Doppler effect, where light waves are stretched as an object moves away, causing them to shift towards the red end of the spectrum. Astronomers can use red shifts to determine the speed and direction of an object's movement.
What does the term blue shift refer to?
Blue shift refers to the phenomenon where the light or other electromagnetic radiation from an object shifts towards shorter wavelengths, often resulting in a blue shift in the spectrum. This can occur when an object is moving towards an observer, causing a compression of the waves and a shift towards the blue end of the spectrum.
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
How are Doppler blue and red shift different?
A blue shift is observed in the spectrum from an object approaching the observer whereas a red shift is observed for a receding 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.
