As a light source moves away from Earth, its light waves become stretched out, causing a shift towards longer wavelengths known as redshift. This is due to the Doppler effect, where the frequency of light is altered by the motion of the source relative to the observer. This redshift can indicate that the object emitting the light is moving away from us.

Red Shift
What is the best term to describe how light waves from a star are affected as the star moves away from Earth?
redshift
What happens when the space shuttle takes off and moves away fromm earth?
It masses increases and the weight increases
Why is daytime light and night dark?
Daytime is light because the sun emits light that reaches our atmosphere and illuminates the Earth's surface. Night is dark because the Earth rotates and moves away from the direct sunlight, causing the absence of light reaching the surface.
How many light years away is betelgeuse?
Betelgeuse is approximately 600 light years from Earth.
Is the sun out at night?
yes it is. but the earth moves away from the sun at night and it moves out of its light and into darkness.
What happens to the shadow as this light source moves?
As you move farther away your shadow get bigger and goes away
What is an increase in the wavelength of light as a galaxy moves away from earth?
Red Shift
What is the name for the change in a stars spectrum when it moves away from the earth?
The change in a star's spectrum when it moves away from the Earth is called redshift. This shift occurs because the wavelengths of light emitted by the star are stretched out as the star moves away, causing the light to appear more red.
What happens when the distance from the sun gets larger?
If the Earth moves further away from the sun we will freeze.
What happens to light as it moves away from its source?
As light moves away from its source, it spreads out and becomes less intense. This is known as light attenuation. The further the light travels, the more it scatters and loses energy, resulting in a decrease in brightness.
Why is it light in day time and dark in night time?
Because the earth moves away from the sun
What happens to the wavelength of light as an object is moving away from you?
As an object moves away from you, the wavelength of light appears to lengthen, known as redshift. This is a result of the Doppler effect, where the motion of the object causes the light waves to stretch out. The further the object moves away, the more stretched out the light waves become.
What is the best term to describe how light waves from a star are affected as the star moves away from Earth?
redshift
How can astronomers determine whether star is moving toward 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.
