Which of the following statements about interstellar dust is FALSE

Which of the following statements about interstellar dust is FALSE

A. dust makes distance stars look redder than they should

B. dust scatters blue light from stars

C. dust gives HII regions their red color

D. dust makes distant stars look fainter than they should

Answer: C. dust gives HII regions their red color

This statement is wrongful, since it is the HII regions, that are the clouds made up of ionized hydrogen gas that are in the respective neighborhoods of young, hot, stars, that shine in red color, which is primarily rather due to the hydrogen atoms’ emission, not the stardust between stars.

Interstellar dust is responsible for the following effects:

A. Yes – The dust blocks and removes more blue unsure that as well as red light, hence, stars appear as redder than their normal color.

B. Yes – Therefore, the bluish tint of the scattered light is a result of the blue light particles being deflected close to the white ray of sunlight.

D. Fact – Dust blocks and scatters rays of lamps from stars, thus making stars at the core of galaxies seem fainter than what would not be the case without the dust in between.

On the other hand, every pixel that has reddish nuance indicate the existence of hydrogen atoms are emitted and not the presence of interstellar dust.
