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. how many free electrons in copper https://anthologystrings.com

Stars vary widely in size, mass, brightness, and longevity. The largest are about 100 times the mass of the Sun and about 10 times the Sun’s diameter (while on the main sequence, but later swelling by a factor of 100 as red supergiants). They give off almost a million times as much light as the Sun.
