Answer :
To determine the order of apparent magnitude of the stars from least to greatest distance (which corresponds to the brightest to the dimmest apparent magnitude), we need to sort the stars based on their distances from Earth.
Here are the given distances for each star:
- Star [tex]\( P \)[/tex]: 2.3 light years
- Star [tex]\( Q \)[/tex]: 7.8 light years
- Star [tex]\( R \)[/tex]: 6.5 light years
- Star [tex]\( S \)[/tex]: 3.2 light years
Next, we arrange these stars in ascending order of their distances:
1. Star [tex]\( P \)[/tex]: 2.3 light years
2. Star [tex]\( S \)[/tex]: 3.2 light years
3. Star [tex]\( R \)[/tex]: 6.5 light years
4. Star [tex]\( Q \)[/tex]: 7.8 light years
Thus, the order of apparent magnitude of the stars, starting from the least to the greatest distance (or equivalently from the brightest to the dimmest) is:
[tex]\[ P, S, R, Q \][/tex]
So, the correct answer is:
[tex]\[ P, S, R, Q \][/tex]
