What instrument is used to tell what a star is made of?
Spectrometers are used for this. By looking at the spectrum of light coming from the star, scientists can tell which elements are in the star by the pattern of lines that are known to be associated with certain elements.
What does a star's color tell you about the amount of energy it emits?
The color of the star is white which shows emission of light & huge energy. If we hold a glowing torch in front of our eyes, our eyes constricts i.e. emission of strong light. But if we hold a torch glowing dimly we will see that our constricts less i.e. the power of the light is less. The same occurs in the stars,bright white light means emission of huge energy.
The light from stars are used to determine what?
The light from stars can tell us what type of star it is (our Sun is a G type), the stars spectrum can tell us what elements are in the star, and its intristic brightness can help us determine how far away it is. Also, if there is a wobble in the star, or a change it the stars brightness can tell us if it has a planet.
What does a star's color tell you about that star?
A star's color indicates its temperature. Hotter stars emit more blue light and appear blue or white, while cooler stars emit more red light and appear red or orange. By studying a star's color, astronomers can determine its temperature and infer other properties like its age and size.
What does a red shift tell astronomers about stars or galaxies?
A red shift in the light emitted by a star or galaxy indicates that it is moving away from us. By measuring the amount of red shift, astronomers can determine the speed at which the object is receding and use this information to study the expansion of the universe and the distance to the object.
How can spectrum tell us if an object is reflecting blue light from a star?
how can you tell if an object is reflecting blue light from a star
What makes light so important?
You can tell how big a star is using light and you can tell what elements it is made from using light.
How do colors tell you about the temperature of a star?
The colder a star is the longer the light waves it emits. Light wavelength is what we perceive as color.

What is the dash light symbol that looks like a candle in a jar on the 2004 ford free star stand for?
your oil light. and it is you tell light looks like a u with a ! in the middle of it
What informatoin can light revael about stars?
Stars' light tells us whether the star is moving toward us or away, it tells us the size of the star, and also the distance the star is from us. Stars light also tells us fairly accurately what different materials it is made of. (Usually hydrogen and helium). Light can also tell us if the star has about used up its hydrogen and so on.
How can astronomers tell if a star may have a planet revolving around it?
There are two ways you can tell if a star may have a planet around it. One way is that the star would have a slight wobble in its motion across our sky. This is caused by the planet's gravitational pull on the star which would cause a slight movement or shift in its alignment. More easily detectable by modern telescopes would be a periodic reduction in the level of light coming from the star. The key is the period in which the light reduction occurs, which would offer a clue as to the period of the orbit of the planet around the star as it blocks light during its orbit.
Why all-stars have light?
Stars undergo nuclear fusion in their cores, and so generate energy; i.e., light and heat. No nuclear fusion, no energy generation, ergo not a star at all. Generating light and heat is how we can tell a very large planet from a star. If it isn't generating energy from nuclear fusion, then it isn't a star.
Can fish tell when it's spring?
Yes, a fish can tell when it is spring or winter as long as it can see the change in the amount of time there is light. Their brains detect when the day or night is longer or shorter, which will tell it the season. Some breeders use this to trick the fish into thinking it is time to breed by altering the amount of time the fish see light each day.
What does a star's color tell you about that star?
A star's color indicates its temperature. Hotter stars emit more blue light and appear blue or white, while cooler stars emit more red light and appear red or orange. By studying a star's color, astronomers can determine its temperature and infer other properties like its age and size.
