Redening of light from a certian density of particals

In summary, the redening of light refers to a shift towards the red end of the visible light spectrum when light passes through a medium with a high density of particles. The higher the density, the more significant the shift. Any type of particle can cause redening, and it is not the same as the red shift observed in astronomy. Redening can be reversed by removing particles or allowing light to travel through a less dense region.

i am trying to find a value for z or the redshift of light that would be caused by a certian density over a certian distance?
if anyone has a formula or knows of a place i can find out what resurch has been done it would be of great help thanks

The reddening of light by dust or gas is not the same as a "redshift". When a spectrum changes by "reddening", the entire spectral shape changes. When it changes by redshift, it just shifts in frequency/wavelength.
 

1. What is the redening of light from a certain density of particles?

The redening of light is a phenomenon that occurs when light passes through a medium with a high density of particles. This causes the light to scatter and lose some of its energy, resulting in a shift towards the red end of the visible light spectrum.

2. How does the density of particles affect the redening of light?

The higher the density of particles in a medium, the more likely it is for light to scatter and undergo redening. As the density increases, the amount of light that is scattered also increases, resulting in a more significant shift towards the red end of the spectrum.

3. What types of particles can cause redening of light?

Any type of particle can cause redening of light, as long as there is a high enough density of them in the medium. This can include dust particles, gas molecules, and even tiny particles in liquids.

4. Is redening of light the same as the red shift in astronomy?

No, redening of light is not the same as the red shift observed in astronomy. Red shift refers to the stretching of light waves as they travel through space, which is caused by the expansion of the universe. Redening of light, on the other hand, is caused by the scattering of light in a dense medium.

5. Can redening of light be reversed?

Yes, redening of light can be reversed by removing the particles from the medium or by allowing the light to travel through a less dense region. This can be seen in the sky during sunrise and sunset, where the redening of light caused by the Earth's atmosphere is reversed as the sun rises above or sets below the horizon.
