What is the apparent brightness of a star as represented by a number on a logarithmic scale?
The apparent brightness of a star is represented by its apparent magnitude, which is a logarithmic scale used to measure the brightness of celestial objects as seen from Earth. The lower the apparent magnitude number, the brighter the star appears in the sky. Each increase of one magnitude corresponds to a brightness factor of 2.5.

Why can apparent magnitude be a misleading number?
Apparent magnitude can be a misleading number because they do not necessarily correspond with the actual brightness of the star. The apparent magnitude is the number given to a star based on how bright it looks.
Is apparent magnitude an indicator of a star's temperature?
The apparent magnitude of a star is a measure of its brightness as seen from Earth, the lower the number, the brighter a star is. Ex. a star that has an apparent magnitude of -20 is WAY brighter from Earth than a star with a apparent magnitude of 20.
The true brightness of a star is called its BLANK magnitude?
The scale of star brightness is the 'magnitude'. The definition of the magnitude is: A change of six magnitudes equals a factor of 100. So one magnitude change is a factor equal to the 6th root of 100 = about 2.15443 (rounded)
The azimuthal quantum number is represented by what letter?
The azimuthal quantum number is represented by the letter "l".
The brightness of stars as they appear from Earth is measured by magnitude?
Stars are measured in brilliance called magnitude. The faintest stars visible to the naked eye are mag.6. Brighter ones are mag. 1 or 2, the even brighter stars have negative magnitude. So its like a number line in math: Brighter Fainter -6_-5_-4_-3_-2_-1__0__1_2_3_4_5_6
What is the unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is the standard unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.

How is stars brightness measured from earth?
Astronomers use a special term to talk about the brightness of stars. The term is "magnitude". The magnitude scale was invented by the ancient Greeksaround 150 B.C. The Greeks put the stars they could see into six groups. They put the brightest stars into group 1, and called them magnitude 1 stars. Stars that they could barely see were put into group 6. So, in the magnitude scale, bright stars have lower numbers.

What is apparent magnitude.?
The apparent magnitude (m) of a celestial body is a measure of its brightness as seen by an observer on Earth, normalized to the value it would have in the absence of the atmosphere.The brighter the object appears, the lower the value of its magnitude.The variation in brightness between two luminous objects can be calculated by subtracting the magnitude number of the brighter object from the magnitude number of the fainter object, then using the difference as an exponent for the base number 2.512; that is to say (mf − mb = x; and 2.512x = variation in brightness).For example:What is the ratio in brightness between the Sun and the full moon?The apparent magnitude of the Sun is -26.73, and the apparent magnitude of the full moon is -12.6. The full moon is the fainter of the two objects, while the Sun is the brighter.Difference in magnitudex = mf - mbx = (-12.6) - (-26.73) = 14.13Variation in Brightnessvb = 2.512vb = 2.51214.13vb = 449,032.16variation in brightness = 449,032.16In terms of apparent magnitude, the Sun is more than 449,032 times brighter than the full moon.For more information [See Link]
How can tell how bright a star really is?
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).
What is antilogarithm?
The Logarithm of a number is the converse of its logarithmic value..
Is magnitude a noun?
Yes, the word 'magnitude' is a noun, a word for the great size or extent of something; the importance of something in influence or effect; the degree of brightness of a star, as represented by a number on a scale; the intensity of an earthquake represented by a number on a scale.
Magnitude is an earthquake's what?
The magnitude of an earthquake is caluated to measure the amount of energy released during the earthquake.
What decimal number is represented by the binary number?
Every decimal number can be represented by a binary number - and conversely.
