How would the absorption spectrum of an atom differ from its emission spectrum? How could one measure an absorption spectrum?
absorption is the exact oppositve from the emission
so for every emission spectrum line, there will be a line per electron transition
for the absorption line, expect a black line in the previous lines
for all the absorbed --> there is the reversed emission line

True statements about the absorption and emission of energy by an atom include which of the following? I. An atom can only absorb photons of light that have certain specific energies. II. An atom can emit photons of light of any energy. III. At low temperature, the lines in the absorption spectrum of an atom coincide with the lines in its emission spectrum that represent transitions to the ground state. A. I only B. III only C. I and III...
- White light spectrum – a. How does the spectrum of white light differ from the spectrum of hydrogen, neon and sodium? b. What color corresponds to 5.7 x 10-7 meters? _____________________________ - Hydrogen Emission Spectrum – There are several lines with colors and 3 lines which are white. The white lines are in the infrared region and not visible. a. Which line in the visible spectrum has the longest wavelength and lowest energy? ______________________ b. Figure 6.1 in the lab manual represents the Balmer...
1. How many lines would be in the emission spectrum of hydrogen if the hydrogen atom had only 4 energy levels? 2. What was the initial energy level of an electron if it was excited by a photon of wavelength 0.656µm and jumped to an energy level of 3? 3 .Calculate the frequency of visible light emitted by electron drop from n=233000 in Balmer series of hydrogen atom.
1.explain why there are more lines in the hydrogen emission spectrum than in the absorption spectrum? 2. indicate asborption, from a lower energy level to a higher energy level. Then indicate emission for the same transition as through various pathways, which would then result in many more emission peaks than there was in the original absorption (transition).
How would the absorption and emission spectra of a powdered 1:1 GaP and GaAs physical mixture differ from the spectra that would be seen for a GaP0.5As0.5 solid solution?
A. Describe the spectrum you would observe for the emission spectrum of elemental hydrogen gas. B. Describe the spectrum you would observe for the absorption spectrum of elemental hydrogen gas.
An atom has only has two absorption lines, at 300 nm and 450 nm. What is the wavelength of the one line in the emission spectrum which does not appear in the absorption spectrum.
would an emission spectrum of an unknown sample be a good way to qualitatively identify which elements are present? What information would you look for in an emission spectrum to allow you to determine quantitative information? In other words, how could you tell how much of a certain element was present?
The absorption spectrum for the molecule fluorescent
is shown here in part (A) along with the fluorescence spectrum when
excited at 488nm. How would the fluorescence spectrum change if
this same sample was excited with a source at 440nm with the same
intensity as the 488 source? Roughly sketch an overlay of the two
fluorescence spectra when excited at 440nm.
