Exam-style question
Try this first
If two stars have absolute magnitudes of +1 and +5 respectively, how do their luminosities compare qualitatively?.
Model answer
What a good answer should say
- The star with an absolute magnitude of +1 is more luminous than the star with an absolute magnitude of +5.
- This indicates that the first star emits more energy than the second star.
Explanation
Why this works
This answer effectively interprets the magnitude scale, showing that a lower absolute magnitude corresponds to higher luminosity. It tests the student's ability to qualitatively compare the brightness of stars based on their absolute magnitudes.
