What creates the difference between apparent brightness and absolute brightness?
Apparent brightness is how we see the star’s brightness from Earth. The absolute brightness is what a star would look like if there was a standard distance that we were looking at all of the stars from.
What is the difference between absolute brightness and apparent 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.
What is the difference between absolute magnitude and apparent magnitude quizlet?
What is the difference between apparent and absolute magnitude? Apparent magnitude is how bright a star appears from Earth and depends on brightness and distance to a star. Absolute magnitude is how bright a star would appear from a standard distance.
What is the difference between apparent and intrinsic brightness?
The luminosity of a star is its intrinsic brightness, that is, the amount of energy that the star radiates per second in all directions. Also referred to as absolute brightness or absolute magnitude. The apparent brightness of a star is how bright it actually appears to an observer.
What does intrinsic brightness mean?
Filters. The brightness a star would have if not attenuated by distance or intervening gas or dust. As opposed to apparent brightness which it has as measured at a distance.
Is brightness same as luminosity?
Luminosity is the objects true brightness measured from its place in the universe (or the torch in this example). Brightness is the objects apparent brightness measured from Earth (or the eye in this example).
Why do stars differ in intrinsic brightness?
Stars have a wide range of apparent brightness measured here on Earth. The variation in their brightness is caused by both variations in their luminosity and variations in their distance. Again, think of the luminosity—the energy emitted per second by the star—as an intrinsic property of the star.
What makes a flame white?
Magnesium sulfate: Makes a white flame. Strontium chloride: Makes a red flame. Copper chloride: Makes a blue flame. Lithium chloride: Makes a pink flame.
What burns a blue flame?
A Blue Flame Indicates Complete Burning of Carbon If you’re using a gas grill or stove, you may discover a blue flame. Propane gas, like firewood, contains carbon compounds.
What color flame is potassium?
Colors of Other Elements
|K||Potassium||Light purple to red|
|Li||Lithium||Deep pink to dark red|
What causes a flame?
Fire is the result of applying enough heat to a fuel source, when you’ve got a whole lot of oxygen around. As the atoms in the fuel heat up, they begin to vibrate until they break free of the bonds holding them together and are released as volatile gases. These gases react with oxygen in the surrounding atmosphere.
What is blue fire called?
With complete combustion, methane burns with a blue flame color (natural gas blue flame) and burns at a temperature of around 1,960°C.
How do you describe a flame?

What is flame in simple words?
A flame is the visible part of a fire. It gives light and heat. It is the result of an exothermic reaction. The color and temperature of a flame depend on the type of fuel that is used to make the fire. A blue or white flame is often very hot, while a red, orange, or yellow flame is less hot.
