A certain star is 12.4 times dimmer than a star with apparent magnitude m = 3.6. What is the apparent magnitude of the dimmer star?
Added by Montserrat M.
Step 1
This means that a difference of 1 in magnitude corresponds to a brightness ratio of approximately 2.512 (the fifth root of 100). So, if a star is 12.4 times dimmer than a star with an apparent magnitude of 3.6, we need to find out how many "steps" of 2.512 this Show more…

The apparent magnitude of a star is the measure of its brightness as seen by someone on Earth. The smaller the apparent magnitude, the brighter the star. Use the apparent magnitudes in the table to answer Exercises 77 through $\overline{82}$. Which is dimmer, Antares or Spica?
