Star X has an apparent magnitude of 3, and star Y has an apparent magnitude of 8. How do they compare in observed brightness?

Question

Quizplus · Accepted Answer

The apparent magnitude scale is logarithmic, where a difference of 5 magnitudes corresponds to a brightness factor of 100. Since star X has a lower magnitude number, it is brighter, and the difference in magnitude between star X (3) and star Y (8) is 5, meaning star X is 100 times brighter than star Y.
