For example, if alpha Orionis fades by 3 percent, then its magnitude increases by about 0.03 mag. This rule is accurate to about ten percent -- the real change corresponding to fading by 3 percent is about 0.033 mag, not 0.030 mag. my lil shit feat. kodak black syko bob lyrics

WebJun 19, 2010 · At any point x and y, the intensity is equal to the square of the amplitude. Not in SI units, or Gaussian-cgs units either. Assuming "the amplitude" refers to the electric field (And I can't imagine what else it would mean.) (Electric field) 2 has units of energy/m 3 in Gaussian units, or [energy/ (charge*distance)] 2 in SI units. Two of the main types of magnitudes distinguished by astronomers are: • Apparent magnitude, the brightness of an object as it appears in the night sky. • Absolute magnitude, which measures the luminosity of an object (or reflected light for non-luminous objects like asteroids); it is the object's apparent magnitude as seen from a specific distance, conventionally 10 parsecs (32.6 light years).
