.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

22. We can infer the absolute magnitude of pulsating variable stars by measuring their pulsation periods. The longer the pulsations - the greater their luminosities. We then again measure their apparent magnitudes - compare it with their absolute magnitu
