See more WebIf m1 and m2 are the magnitudes of two stars, then we can calculate the ratio of their brightness ( b 2 b 1) using this equation: m 1 − m 2 = 2.5 log ( b 2 b 1) or b 2 b 1 = 2.5 m 1 − m 2. Here is another way to write this equation: b 2 b 1 = ( 100 0.2) m 1 − m 2. Let’s do a real example, just to show how this works. fitness superstore discount code 2021
