Magnitude

In Mathematics , the Magnitude of an object is a Non-negative Real Number associated with that object.

In Physics , the magnitude of a Vector is a Scalar in the physical sense, i.e. a Physical Quantity independent of the Coordinate System , expressed as the Product of a Numerical Value and a Physical Unit , not just a number.

In Astronomy , Magnitude refers to the Logarithm ic measure of the brightness of an object, measured in a specific Wavelength or passband, usually in Optical or near- Infrared wavelengths. Two specific types of magnitudes distinguished by astronomers are ''' Apparent Magnitude ''' and ''' Absolute Magnitude '''. Furthermore, the term may also refer to the ''' Magnitude Of An Eclipse '''.

In Seismology , the magnitude is a logarithmic measure of the energy released during an Earthquake . See Richter Scale and Moment Magnitude Scale .
