What term is used to describe a star's brightness?
It is called Vmag. This is the visual magnitude of the object. Visual magnitude is a scale used by astronomers to measure the brightness of a star or other celestial object. Visual magnitude measures only the visible light from the object. The lower the V-MAG the brighter the star. You can go to http://seasky.org/pictures/sky7b14.html to learn more.
Why do scientists prefer the moment magnitude scale over the righter scale?
Richter scales are useful to measure only small, shallow earthquakes recorded within a certain distance from the epicenter. A moment magnitude scale is more precise than a Richter scale. It also gives a measure of the energy released during an earthquake.
The measure of a stars brightness is called its what?
Scientists actually use two measurements to identify a star's brightness. One is luminosity, or the energy that star puts out. Another is magnitude, or the amount of light a star puts out.
Is a star luminous?
Yes, stars are luminous.Stars emit energy in the form of light. The immense temperature and pressure inside stars fuses atoms together in a process called nuclear fusion. This releases energy, largely in the form of light and heat. Some stars shine more brightly than others and this brightness is known as the star's magnitude. There are two types of magnitude.1. Apparent magnitude - This is a measure of how bright the Star appears to us (this does not take into account how far away from us the star is).2. Absolute magnitude - A measure of how bright the star actually is once we allow for distance (if it is further away it will appear to be less bright to us but this scale compensates for this).
If Refers To The Size Or Strength Of The Force?
The "size" of a vector quantity - such as a force - is often called a MAGNITUDE.
What is an earthquake's magnitude a measure of?
An earthquake's magnitude is a measure of how strong it is
What are the standard units used to measure the magnitude of earthquakes?
The standard units used to measure the magnitude of earthquakes are the Richter scale and the moment magnitude scale.
What is a sentence with magnitude?
The magnitude of an earthquake is a measure of the energy that is released by the event.
What scale is used to measure the strength (magnitude) of an earthquake?
Richter Magnitude
What is magnitude and how is it measured?
magnitudea measure of the amount of the energy released by earthquake . earthquake is measure through Ricthter scale that measure the magnitude of seismic waves that it has
How bright a star appears as seen from earths is called?
The apparent magnitude.
What are the measure of the strength of an earthquake is called?
The Richter magnitude scale is used to measure the strength of an earthquake.
What is the measure of an earthquakes strength called?
This is known as magnitude. It is measured on the moment magnitude scale.
Use apparent magnitude in a sentence?
The apparent magnitude of a star is a measure of its brightness.
What is the measure of a stars brightness?
Magnitude.
What is apparent and absolute magnitude?
Apparent magnitude is the measure of how bright a star appears to be from our vantage point. Absolute magnitude is the measure of how bright a star would be if it were located 10 parsecs from earth.
What term means the measure of energy released by an earthquake?
The measure of energy released by an earthquake depends on its magnitude. If its a high magnitude earthquake, there is a lot of energy. If there is a low magnitude, then there is little energy.
