When a wavelength is moving away, it becomes stretched out and its frequency decreases. This phenomenon is known as redshift and is commonly observed in the context of the expanding universe.

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.


Which color has the longest wavelength and shows that a star is moving away from us?

It's not that a particular color has the longest wavelength. The wavelength BECOMES longer when a star moves away from us. Red light has a longer wavelength than blue, for example.


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.

What light has the same causes as the pitch of sound?

Stars in the universe are all moving away from us, so their wavelength will be red shifted. When the source of a sound is moving away from us, the wavelength of the sound will increase, i.e. the frequency will lower. In both cases, this is known as Doppler shift.


What you get when stars are moving away?

When stars are moving away from us, we observe a phenomenon called redshift. This redshift occurs because the light from the stars is stretched, causing its wavelength to become longer. The greater the redshift, the faster the star is moving away from us.


How are red-shifted and blue-shifted waves different?

The "doppler effect" (see link below) describes what happens to an observer who is moving toward or away for the source of any type of propagation wave such as light or sound.If we are moving rapidly toward any object which is transmitting an electromagnetic wave - or if it is moving toward us - the waves are "compressed" and we perceive them to be of a higher frequency than was originally emitted. With light, "higher frequency" means "more bluish", while "lower frequency" means "more reddish".So scientists refer to the increasing wave frequency as a "blue shift", while a decreasing frequency, meaning movement away from us, is a "red shift".


Would a slow moving proton or a fast moving golf ball have a larger wavelength?

fast moving Golf ball.


What happens to the wavelength of the sound as it moves away from you?

As sound moves away from you, the wavelength stays the same but the frequency decreases, causing the pitch to sound lower. This is because sound waves spread out as they travel and the distance between wave peaks increases, resulting in a longer wavelength.


Which has a larger wavelength a slow moving photon or a fast moving golf ball?

A slow moving photon has a longer wavelength compared to a fast moving golf ball. Wavelength is inversely proportional to speed, so the slower the object, the longer the wavelength.


How can the Doppler effect determine if things are moving towards a distant galaxy or away from one?

Light had properties of frequency that related to colour. It is apparently contract in the direction moving toward the observer (higher frequency-short wavelength) and apparently elongated in the direction moving away from observer (lower frequency-high wavelength). What moving toward us is tend to be look more blue than usual (blue shift) and what away from us is redder than usual (red shift).


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.
