what is the difference between apparent magnitude and absolute magnitude?

Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.

The absolute value of an integer or floating point number is the number without its positive or negative sign. The absolute value of a vector is a vector with components stripped of negative signs. translateY = abs( sin(time) ); the absolute value of the sine wave makes for a good bouncing action.

As nouns the difference between frequency and magnitude is that frequency is (uncountable) the rate of occurrence of anything; the relationship between incidence and time period while magnitude is (uncountable|countable) the absolute or relative size, extent or importance of something.

Matrices and Absolute Value. Join us as we enter The Matrix. ... Absolute values determine the magnitude of a number or how 'large' it is. In other words, absolute values don't care if a number is positive or negative; they only care about how far a number is away from 0.

It is important not to confuse the just noticeable difference and the absolute threshold. ... While the difference threshold involves the ability to detect differences in stimulation levels, the absolute threshold refers to the smallest detectable level of stimulation.

The difference between Apparent and Obvious When used as adjectives, apparent means capable of being seen, or easily seen, whereas obvious means easily discovered, seen, or understood.

As adjectives the difference between absolute and definite is that absolute is (obsolete) absolved; free while definite is having distinct limits.

The absolute value of a Decimal is its numeric value without its sign. For example, the absolute value of both 1.2 and -1.2 is 1.2.

Apparent magnitude Astronomers now measure differences as small as one-hundredth of a magnitude. Stars that have magnitudes between 1.5 and 2.5 are called second-magnitude; there are some 20 stars brighter than 1.5, which are first-magnitude stars (see the list of brightest stars).

Absolute magnitude. ... An object's absolute magnitude is defined to be equal to the apparent magnitude that the object would have if it were viewed from a distance of exactly 10 parsecs (32.6 light-years), without extinction (or dimming) of its light due to absorption by interstellar matter and cosmic dust.

The magnitude of distance is the length of the whole path you have taken while the magnitude of displacement is the length of the line joining the start point and end point of the journey .

Apparent magnitude vs. Stars that are closer to Earth, but fainter, could appear brighter than far more luminous ones that are far away. ... Another measure of brightness is luminosity, which is the power of a star — the amount of energy (light) that a star emits from its surface.

Also called numerical value. the magnitude of a quantity, irrespective of sign; the distance of a quantity from zero. The absolute value of a number is symbolized by two vertical lines, as |3| or |−3| is equal to 3.

To figure out luminosity from absolute magnitude, one must calculate that a difference of five on the absolute magnitude scale is equivalent to a factor of 100 on the luminosity scale — for instance, a star with an absolute magnitude of 1 is 100 times as luminous as a star with an absolute magnitude of 6.

5 Answers. Usually, size connotes physical dimensions while magnitude connotes either a numerical measure (particularly a non-linear one) of any sort of amount or metaphorical size. You can also use size to mean metaphorical size, but you usually can't use magnitude alone to mean physical size.
