What Is Responsible For The Extinction And Reddening Of Starlight. Extinction dimming of starlight due to interstellar medium star's are completely blocked by dust in some directions. Dust grains interacting with starlight causes reddening by either the absorption or scattering of other colors.

The ism affects starlight which passes through it and the effects of the ism on the observed magnitudes and colours of stars must be allowed for if. Since blue light is much more strongly attenuated than red light, extinction causes objects to appear. Web what causes reddening of starlight? Dust grains interacting with starlight causes reddening by either the absorption or scattering of other colors. Dust grains the size of olives. Web what is responsible for the extinction and reddening of starlight? Dust grains interacting with starlight causes reddening by either the absorption or scattering of other colors and we only can see the reddening one because other colors have longer wavelength that we cannot see. Both a and b above. Dust grains with diameters near the wavelength of light. Web since both interstellar reddening and extinction are the result of the interaction of starlight with dust grains, they are inextricably linked and we should expect that the more dust along the line of sight, the more pronounced the reddening and the higher the extinction.
Dust grains with diameters near the wavelength of light. Web a interstellar extinction and reddening interstellar space is not empty but is permeated by the interstellar medium (ism). Dust grains interacting with starlight causes reddening by either the absorption or scattering of other colors and we only can see the reddening one because other colors have longer wavelength that we cannot see. Web what is responsible for the extinction and reddening ofstarlight? Web interstellar reddening dust grains along the line of sight scatter and absorb light coming from distant objects. H2 and complex organic molecules only form in dark clouds because the accumulation of dust blocks out starlight. H2 and complex organic molecules only form in dark clouds because the accumulation of dust blocks out starlight. H2 and complex organic molecules only form in dark clouds because the accumulation of dust blocks out starlight. Since blue light is much more strongly attenuated than red light, extinction causes objects to appear. Dust grains interacting with starlight causes reddening by either the absorption or scattering of other colors. We therefore see these objects as dimmer and redder than they really are.
