The doppler shift equation is based partly on the time dilation of the source in your frame--in other words, if a source is emitting wave peaks at a frequency of 5*10^14 per second (visible light) in its own rest frame, then because of time dilation, when it's moving with respect to you it will emit less peaks per second in your frame. In the limit as the velocity of a clock in your frame approaches c, the time between ticks of the clock approaches infinity, no matter how long between ticks in the clock's own frame...so analogously, in the limit as a source's velocity relative to you approaches c, the time between peaks of any signal it emits in your direction approaches infinity too. So I think the answer you're looking for is that the light from a source moving at c would be infinitely redshifted, even though that only makes sense as a statement about limits since a massive light-emitting source cannot actually move at c.Quantum1332 said:if it were possible to see it?

Red shift and blue shift refer to the change in wavelength of light from an object. Red shift occurs when the wavelength of light increases, making it appear more red, while blue shift occurs when the wavelength decreases, making it appear more blue. This phenomenon is caused by the movement of an object towards or away from the observer.
Red shift, specifically cosmological red shift, is a result of the expansion of the universe. As light from distant galaxies travels through the expanding universe, its wavelength is stretched, causing it to appear more red. This is strong evidence for the expansion of the universe and is a key principle in the Big Bang theory.
Yes, blue shift can occur in the universe. This is often seen in objects that are moving towards the observer, such as stars or galaxies that are part of our own galaxy. The blue shift in their light indicates that they are moving closer to us.
Red shift can be used to measure the distance of objects in space through the use of Hubble's Law. This law states that the farther an object is from us, the faster it is moving away from us and the greater its red shift will be. By measuring the red shift of an object, scientists can calculate its distance from Earth.
No, the Doppler effect can apply to any type of wave, including sound waves. In fact, the Doppler effect was first discovered in sound waves, where it is commonly observed in the changing pitch of a siren as it approaches and then passes by an observer. The same principle applies to light waves, resulting in red shift and blue shift.
