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)
How is Avogadro's number represented?
Avagadro's number is represented by the symbols L or NA
The azimuthal quantum number is represented by what letter?
It is represented by l.
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.

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.
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).
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)
What is antilogarithm?
The Logarithm of a number is the converse of its logarithmic value..
Does a stars size affect its magnitude?
It used to make a huge difference. When telescopes were poor and space flight was unheard of. Nowadays the telescopes such as Hubble and Spitzer Infrared mean the we can see exactly how big, bright, and colourful a star is. So to answer the question: To the naked eye, yes. But with a descent telescope, absolutely not.
How do scientists describe magnitude of stars?
Scientists talk about "Apparent Magnitude" and "Absolute Magnitude". The first definition refers to how bright a star appears to us on Earth. The second definition is related to how luminous that star really is. Oddly enough, the brighter a star is, on either scale, the lower the number for its magnitude. The scales are a bit complicated because they are "logarithmic". However, one simple fact is that a difference on of 5 magnitudes means a difference of 100 times in brightness.

What decimal number is represented by the binary number?
Every decimal number can be represented by a binary number - and conversely.
