Why the positions of the dark bands on the absorption spectrum for an element correspond to the bright bands on the emission spectrum of the same element?
It requires a certain amount of energy to raise an electron from a specific level to another specific level; the same amount of energy is released again if it falls back down. One - the electron moving up an energy level - corresponds to the absorption of energy; the other - the electron falling down - corresponds to the emission of energy.
Who are Brewster-Newton theory?
The two people referred to are David Brewster and Isaac Newton. David Brewster intensively studied absorption spectroscopy. These researches led him to dissent from Newton's doctrine of colors and to affirm a "Newtonian" emission theory of light. By 1831 he had determined that the light spectrum "consists of three spectra of equal length, beginning and terminating at the same points, viz. a red spectrum, a yellow spectrum, and a blue spectrum."
Is chloroplast found in both animal cells and plant cells?
Nope. It is only in plant cells. The mitochondria is basically the same thing as a chloroplast, only it is found in animal cells. Plant Cell - Chloroplast Animal Cell - Mitochondria
Do the rainbow and the spectrum have the same or opposite colors?
A rainbow is a spectrum.
How do plants inherit their characteristics?
Yes, not every plant is the same. Example - If you had 5 same types of plants and you looked closely at them, you would probably find differences in them.
How a star is similar to the sun if it has the same absorption lines in its spectrum that occur in the suns spectrum?
because they will have the same elements in the atmosphere...
How a star is similar to the sun if it has the same absorption lines in its spectrum that occur in the sun spectrum?
because they will have the same elements in the atmosphere...
What can be said about the star composition if the spectrum of a star shows the same absorption lines as the sun?
If the spectrum of a star shows the same absorption lines as the sun than you know that the star has the same composition as the sun. This means that the star is made of the same elements as the sun.
How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
An emission spectrum depend on electrons transition in the atom of a chemical element; and elements are different.Absorption spectrum is based on the different absorption pics of different molecules, depending on the frequency of radiation.Spectral methods are largely used in analytical chemistry.
Does the action and absorption spectrum have to be the same?
No, though I can't think why and what the 'action' might be.
How can you Distinguish absorption spectrum from emission spectrum?
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
How a star is similar to the sun if it has the same absorption lines in its spectrrum that occur in the sun's spectrum?
Because the sun is a star
How is a star simmular to the Sun if it has the same absorption lines in its spectrum that occur in the Sun's spectrum?
because they will have the same elements in the atmosphere...
What organ of the plant that conducts light absorption?
Plant leaves that carry out photosynthesis absorb light energy for the same. By this, plant can synthesize the nutrient needed for its survial.
Why do black lines appear on a star's absorption spectrum?
The lines indicate which atoms are in the outer layers of stars. The location of the lines is always the same when they form.
Is there a material that converts only ultraviolet light into electricity?
Every element has an absorption spectrum and almost all of them have a few lines in the UV that will absorb EM energy. Now when we talk of 'converting into electricity' we almost always talk of metals as they are the ones that conduct electricity. It is possible to do the same with non-metals but it is trickier. Now no metal (or element for that matter) will have an absorption spectrum exclusively in the UV. They may have a particularly receptive cluster of lines in the UV but every element will have lines elsewhere as well. For example the element Selenium is particularly suited for detecting light in the visible range.
Why the positions of the dark bands on the absorption spectrum for an element correspond to the bright bands on the emission spectrum of the same element?
It requires a certain amount of energy to raise an electron from a specific level to another specific level; the same amount of energy is released again if it falls back down. One - the electron moving up an energy level - corresponds to the absorption of energy; the other - the electron falling down - corresponds to the emission of energy.
