Magnitude may refer to:
In mathematics:
- Magnitude (mathematics)Magnitude (mathematics)The magnitude of an object in mathematics is its size: a property by which it can be compared as larger or smaller than other objects of the same kind; in technical terms, an ordering of the class of objects to which it belongs....
, the relative size of a mathematical object - Magnitude (vector), a term for the size or length of a vector
- Scalar (mathematics)Scalar (mathematics)In linear algebra, real numbers are called scalars and relate to vectors in a vector space through the operation of scalar multiplication, in which a vector can be multiplied by a number to produce another vector....
, a quantity defined only by its magnitude - Euclidean vector, a quantity defined by both its magnitude and its direction
- Order of magnitudeOrder of magnitudeAn order of magnitude is the class of scale or magnitude of any amount, where each class contains values of a fixed ratio to the class preceding it. In its most common usage, the amount being scaled is 10 and the scale is the exponent being applied to this amount...
, the class of scale having a fixed value ratio to the preceding class
In astronomy:
- Magnitude (astronomy)Magnitude (astronomy)Magnitude is the logarithmic measure of the brightness of an object, in astronomy, measured in a specific wavelength or passband, usually in optical or near-infrared wavelengths.-Background:...
, a measure of brightness and brightness differences used in astronomy- Apparent magnitudeApparent magnitudeThe apparent magnitude of a celestial body is a measure of its brightness as seen by an observer on Earth, adjusted to the value it would have in the absence of the atmosphere...
, the apparent brightness of a celestial object as observed from Earth - Absolute magnitudeAbsolute magnitudeAbsolute magnitude is the measure of a celestial object's intrinsic brightness. it is also the apparent magnitude a star would have if it were 32.6 light years away from Earth...
, the brightness of a celestial object corrected to a standard luminosity distance - Photographic magnitudePhotographic magnitudeBefore the advent of photometers which accurately measure the brightness of astronomical objects, the apparent magnitude of an object was obtained by taking a picture of it with a camera. These images, made on photoemulsive film or plates, were more sensitive to the blue end of the visual spectrum...
, the brightness of a celestial object corrected for photographic sensitivity, symbol mpg
- Apparent magnitude
- Magnitude of eclipseMagnitude of eclipseThe magnitude of eclipse or geometric magnitude is the fraction of the diameter of the eclipsed body which is in eclipse. This applies to both solar eclipses and lunar eclipses. During a partial or annular eclipse the magnitude of the eclipse is always between 0.0 and 1.0, while during a total...
or geometric magnitude, the size of the eclipsed part of the Sun during a solar eclipse or the Moon during a lunar eclipse
As an earthquake unit of measure:
- Richter magnitude scaleRichter magnitude scaleThe expression Richter magnitude scale refers to a number of ways to assign a single number to quantify the energy contained in an earthquake....
,a measure of the energy of an earthquake - Moment magnitude scaleMoment magnitude scaleThe moment magnitude scale is used by seismologists to measure the size of earthquakes in terms of the energy released. The magnitude is based on the seismic moment of the earthquake, which is equal to the rigidity of the Earth multiplied by the average amount of slip on the fault and the size of...
, an alternative to the Richter scale for measuring earthquakes - Surface wave magnitudeSurface wave magnitudeThe surface wave magnitude scale is one of the magnitude scales used in seismology to describe the size of an earthquake. It is based on measurements in Rayleigh surface waves that travel primarily along the uppermost layers of the earth...
