How is spectral analysis used in light sources?
Spectral analysis is a procedure in which a light source is shone through a lens to reveal its components. Light created by different methods have different spectral components, which act like a fingerprint. For example, if you examine the spectrum of a distant star, the different wavelengths will show you what different elements comprise that star. At a more detailed scientific level, the individual lines are determined by the amount of energy lost by a particular atom's electrons as they move between energy levels. Each energy level of an atom's electron shell is characteristic to that atom. When an electron moves from a higher energy level to a lower one, there is a release of energy in the form of a photon, and that photon's wavelength is determined by the amount of energy change, resulting in a spectrographic line characteristic to that atom.
What does a stars dark line spectrum reveal?
The dark lines reveal the atoms that are associated with the stars atmosphere. The dark lines are atom energy absorption signatures.
What does the spectrum of a solar prominence reveal?
the influence of stochasticity on nonlinear population.
How do astronomers tell if a star is binary or has planets?
a way to tell if a star has planets is to observe a wobble in its position. i.e when a planet orbits a star it pulls at it making the star move slightly in its direction. when seen from far away it looks like the star is moving back and forth. This is a very rough explanation and can no doubt be improved upon.
How can the color of starlight reveal the temperature of a star?
The colour of starlight reveals the temperature of a star by wavelengths in the electromagnetic spectrum, to give a measuring tool for star temperature.
What did the existence of galaxies reveal about the size of the universe?

Can the Doppler effect reveal the rotation speed of a star by the splitting of the spectral lines?
Yes that is true! Astronomy homework?
What do temperatures reveal about motion of its particles?

What can graphs reveal about linear motion of an object?
It lets us know how the object can zig-and zag.
What is a motion of discovery for a dcfs case?
One side, or the other, has made a motion that the opposing side reveal what evidence and witnesses they are going to present at the hearing or trial.
What is the name of the motion called to reveal to reveal presonal files of police officers?
You may be thinking of a Freedom of Information act, but I don't think that will work. You'll have to check with an attorney.
What are the main indicators the suggest there is something with a large amount of gravity at the center of many galaxies?
Significant indicators that there is something which exerts a large amount of gravitational force at the center of galaxies includes the motion of matter revolving around it. This motion, for example stars orbiting around the galactic nucleus, upon close study can reveal the amount of mass present. Note that galaxies don't necessarily have to have mass at their nucleus - stars can of course be simply in orbit around a common center of gravity. Other indicators include the presence of a powerful x-ray source in that location, or the presence of relativistic jets perpendicular to the plane of the galaxy consistent with models for the behaviors of high mass objects.
What fossils are helpful to geologist because they reveal the relative ages of the rock layers in which they occur?
Those types of fossils are called index fossils.
How do you use the reveal in a sentence?
They will reveal the winners after the ceremony. When will you reveal your news?
How can you see and photograph distant galaxies throughout the universe but you can't even see most planets in the milky way galaxy?
Galaxies are a whole lot bigger than planets. And astronomical pictures (x-rays, visible light, etc,) don't reveal much about individual stars, much less planets, within them. Astronomers have become very good at figuring out quite a bit about the Universe from pretty scant data.
How do you use reveal and expectations in a sentence?
Just reveal your expectations and we can get started.
What are witnesses obliged to reveal?
