What is the name of the amount of light a star gives off?

The amount of light a star gives off is the intensity or luminosity. Absolute Magnitude measures the amount of light given off.


The amount of light a star gives of is called its?

The sun give light to the star because the sun reflects on the star to give them light.


A star's brightness is determined by the amount of light it gives off and its distance from?

The observer.


Is the apparent magnitude of a star the amount of light is actually gives off?

No. It's what we see. (The amount it actually gives off is called the absolute magnitude.)


What is the actual amount of light a star gives off called?

The actual amount of light a star gives off is called its luminosity. Luminosity is a measure of the total amount of energy emitted by a star per unit time, typically expressed in terms of watts or solar luminosities. Luminosity is a crucial parameter in understanding the characteristics and evolution of stars.


What is the actual amount of light a star gives off?

It is actually absolute magnitude, opposed to apparent magnitude which is how much light stars appear to give off.


The amount of light a star gives off is called what?

its called magnitude or luminosity. :) hope it helped you.


What is the amount of light a star gives off?

It's electromagnetic radiation, part of the spectrum of which is visible light. The question actually asks what is the AMOUNT of light a star gives off. So we are looking for a quantity here, measured in photons. In relative terms we use absolute and absolute magnitude. [See related question]

What term is used to describe the actual amount of light given off by a star at a standard distance?

The term used to describe the actual amount of light given off by a star at a standard distance is "absolute magnitude." This measurement helps astronomers compare the true brightness of stars by standardizing it for a set distance of 32.6 light-years.


What is a body of gas that gives off tremendous amount of radiant energy in the form of light and heat?

A star is a body of gas that gives off tremendous amounts of radiant energy in the form of light and heat through nuclear fusion reactions in its core.
