http://burro.astr.cwru.edu/Academics/Astr221/StarProp/dust.html WebInterstellar reddening is caused by the preferential absorption of blue light over red light. Image source Interstellar medium is the material between the stars, made up of dust and gas. In places the matter is very thin and tenuous, other places the dust is very thick and can obscure the light from faraway stars. Image source

Webstarlight passed through. Dust and air in the atmosphere also dims and reddens starlight... The longer the path length the starlight traverses through the atmosphere, the more it is dimmed. Thus, a star close to the horizon will be dimmed more than one close to the zenith. The path length through the atmosphere is known as the air mass.

This analogy illustrates why answer WebStarlight passing through a dust cloud can be affected in a couple of ways. The light can be totally blocked if the dust is thick enough or it can be partially scattered by an amount that depends on the color of the light and the thickness of the dust cloud. All wavelengths of light passing through a dust cloud will be dimmed somewhat. derivative of x 3 2

WebInterstellar dust can be detected: (1) when it blocks the light of stars behind it, (2) when it scatters the light from nearby stars, and (3) because it makes distant stars look both redder and fainter. These effects are called reddening and interstellar extinction, respectively.
