WebIf m 1 and m 2 are the magnitudes of two stars, then we can calculate the ratio of their brightness (b 2 b 1) (b 2 b 1) using this equation: m 1 − m 2 = 2.5 log ( b 2 b 1 ) or b 2 b … 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.

WebThe apparent brightness of each source diminishes with the inverse square of the distance. Therefore, the values of apparent brightness for the three sources at a distance of 2 meters could be 50/2 2 = 12.5 units, 100/2 2 = 25 units, and 200/2 2 = 50 units for the 50, 100, and 200 Watt sources respectively. You will notice that at any distance ... WebKnowing the relative luminance, you may easily calculate the contrast ratio of a colored text by the formula: (L1 + 0.05) / (L2 + 0.05), where L1 and L2 - relative luminance of text and background color (L1>L2). 1. The contrast ratio shows how easily a human recognizes text or image on a colored background.
