SUMMARY
The discussion focuses on the distinction between light reddening caused by dust or gas and redshift, which is a shift in frequency or wavelength. A user seeks a formula to calculate redshift (denoted as z) based on particle density over a specific distance. Fish clarifies that reddening alters the entire spectral shape, unlike redshift, which maintains the spectral shape while shifting it. Understanding these differences is crucial for accurate astrophysical analysis.
