What is an absorption line spectrum and why do stars have absorption line spectra?
The characteristic absorption spectra of two stars are shown. Indicated in each is a set of absorption lines due to interstellar material between us and the stars. Using this information and the spectral drawings shown below complete parts a - e of this question. a. The interstellar absorption lines appear more intense in the spectrum of star A than star B. What does this mean in terms of the number of absorbing atoms between the earth observer's line of sight...
Provide a quantitative explanation to the following question: Why do the spectra of A-type stars show strong Hydrogen Balmer absorption lines, but M-stars have none?
What are the most prominent absorption lines you would expect to find in the spectrum of a star with a surface temperature of (a) 35,000 K, (b) 2800 K, and (c) 5800 K (like the Sun?) Briefly describe why these stars have such different spectra even though they have essentially the same chemical composition.

Astronomy Ranking Task: Doppler Shift Exercise #4 Description: An important line in the absorption spectrum of stars occurs at a wavelength of 656nm for stars at rest. Imagine that you study five stars (A-E) from Earth and discover that this absorption line is observed at the wavelength shown in the table below for each of the five stars. STAR Observed Wavelength of Absorption line A 650 nm B 663 nm C 656 nm D 657 nm E 646 nm...
The absorption spectra of ions have been used to identify the presence of the elements in the atmospheres of the sun and other stars. What is the energy of a photon (in J) that is absorbed by He+ ions, when an electron is excited from the Bohr orbit with n = 1 to the n = 4 state? The energy of an electron in the nth level is:

The absorption spectra of ions have been used to identify the presence of the elements in the atmospheres of the sun and other stars. What is the energy of a photon (in J) that is absorbed by He+ ions, when an electron is excited from the Bohr orbit with n = 1 to the n = 6 state? The energy of an electron in the nth level is? En= -BZ^2/N^2
Exercises After comparing the 100% cranberry juice absorption spectrum to the 100% apple juice aborption spectrum, do you think that apple juice contributes to the color of cranberry-apple juice at the Amax you selected? Why or why not? 2. When you look at cranberry juice and at apple juice, the colors that you see are the parts of the visible spectrum that is not absorbed by the juices. When you look at the absorption spectra of cranberry juice and apple...
