Light waves with 0 amplitude due to extreme red shift?

In summary, light waves cannot be red-shifted to the point where their amplitude is equal to zero. The shift in frequency is not affected by the amplitude of the wave. Moreover, the expansion of space would decrease the energy density and therefore the amplitude, but it would never reach zero.

Is it theoretically/mathematically possible for light waves to be red-shifted so much that it's amplitude is equal to zero?

The shift in frequency is unrelated to the amplitude of the wave as far as I know.

You would need an infinite redshift factor which is unphysical.
If space expands by a factor of 10, the energy density goes down by a factor of 10000, so your amplitude goes down by a factor of 100.
If space expands by another factor of 10, the energy density goes down by another factor of 10000, so your amplitude goes down by another factor of 100.

It will never be zero.
 

Related to Light waves with 0 amplitude due to extreme red shift?

1. What are light waves with 0 amplitude due to extreme red shift?

Light waves with 0 amplitude due to extreme red shift refer to the phenomenon in which light waves become stretched out and lose their energy due to the expansion of the universe. This causes the waves to have a longer wavelength and lower frequency, resulting in a decrease in amplitude.

2. How does extreme red shift affect light waves?

Extreme red shift occurs when an object is moving away from an observer at a high speed, causing the light waves emitted from the object to stretch out and become less energetic. This can make the object appear more red in color and can also cause the light waves to have 0 amplitude.

3. Can light waves with 0 amplitude still be detected?

Yes, light waves with 0 amplitude can still be detected through various methods such as spectroscopy. While the amplitude may be 0, the wavelength and frequency of the light waves can still be measured, providing valuable information about the object emitting the light.

4. What is the significance of light waves with 0 amplitude due to extreme red shift?

Light waves with 0 amplitude due to extreme red shift can provide scientists with important information about the expansion of the universe and the speed at which objects are moving away from each other. This phenomenon also allows us to study the evolution and structure of the universe.

5. Can extreme red shift be observed in everyday life?

No, extreme red shift is typically only observed in astronomical objects that are extremely far away from Earth. In everyday life, we may observe red shift in objects moving away from us, such as the sound of a siren becoming lower in pitch as a car drives away, but this is not the same as extreme red shift seen in the universe.
