Exam 4: Spectroscopy: The Inner Workings of Atoms

Explain how Bohr's model creates emission and absorption lines in the spectrum.

State the relationship between photon energy,frequency,and wavelength.

The larger the redshift,the faster the distant galaxy is rushing toward us.

How can the light reflected off a planet reveal information about its atmosphere,even though the planet is not creating this light?

The Fraunhofer lines in the solar spectrum are actually:

According to Kirchhoff's first law why do dense,hot bodies create the type of spectrum they do?

For hydrogen,the transition from the second to the fourth energy level produces:

In our Sun,the spectral lines of hydrogen are weak,compared to their appearance in hotter stars.

Since the difference in energy between the different rotational states in a molecule is very small,many molecular lines can be observed with:

Which of the following type of electromagnetic radiation has the lowest energy?

The ________ explains why the spectral lines from a rapidly rotating star are broader than those from a slowly rotating star.

In the Bohr model,the transitions of electrons down to ground state produce the Lyman lines in the ultraviolet.

The energy required to move an electron in a hydrogen atom from energy level 2 to energy level 3 is:

Explain how the Zeeman effect allows us to study stellar magnetic fields.
