Apparent Magnitude Problem
 
I am having trouble understanding this problem. It has several parts describing a binary star system. The last part ask for the apparent magnitude of the combined light from both stars, if they were viewed as a single point. I guess my first thought was to add them, but I'm worried because apparent magnitude is a logarithmic scale. Am I overthinking this one?

Thanks

Hi Gammage! :smile:

Yes, you're right to worry

brightness is additive, but magnitude isn't. :wink:
