Can scientists analize the elements of a star?
Scientists can assess which elements are present in the star, by looking at the light it gives off and breaking this light down into the different colours that make up the total colour. They look at the spectrum given off. The different elements present in the star cause different light wavelengths (or colours) to be emitted.
Why did the scientists heat samples of soil from mars?
I don't know, but please answer this question. I need it for school!
Why light emitted by bulb is not monochromatic?
Light bulbs aim to emulate the light emitted by the Sun, which radiates as a black body at 6000 degrees C. The light is emitted over the entire visible spectrum. Some bulbs produce monochromatic light, sodium street lights for example.
What is the difference between emitted light and exciting light?
excited light is the light a chemical absorbs raising it from it's ground state to an excited state. Energy is released as heat and as light. Causes flourescence when chemical returns itself to its ground state. emitted light is the light emitted from the absorbing chemical. When this happens a substance(usually an organic) is emitting a light of longer wavelength after absorbing light of a shorter wavelength.
Does Pluto emit or reflect light?
Pluto reflects the light that was emitted from the sun.

When light waves are emitted by a moving source scientists can measure?
When light waves are emitted by moving source scientists can measure the Doppler effects. It is a source of energy that produces light.

How do scientists identify a star's elements?
c) by its light
Are phosphorus and phosphors the same?
No. Phosphorus is a chemical element; phosphors are materials, not necessarily elements, that emit light slowly enough to be useful light sources in the dark, without the need for applied electric current or other external energy supplies. The light emitted may have been absorbed from the environment experienced by a phosphor before its light is emitted and stored in the phosphor in the form of a metastable excited state of an atom, or it may arise from slow chemical reaction among, or radioactive decay of, one or more constituents of the phosphor.
Why do different elements emits different colored lights when they are subjected to flame?
When the element is subjected to flame, the electrons are in a high energy state. When they come back down to a stable state energy is released in the form of light. The color emitted depends on the amount of energy released.The different colors of the light emitted are caused by the different quantities of electrons losing energy in different elements.
How do astronomers identify elements of the stars?
Elements are identified based on their absorption spectra. Every element absorbs a unique set of frequencies when light passes through it. Scientists can determine which elements are present based on which portions of the star's light are absorbed.
What is a form of emitted light?
fluorescence

What light gets emitted by tanning lamps?
Ultraviolet light
What device is useful for viewing a spectrum of light?
A prism can be used for splitting light into its constituent colors, but scientists tend to use a more precise instrument called a spectrograph.
