The quantum harmonic oscillator is very important in analyzing the spectra of diatomic molecules. It can also be extended to the analysis of polyatomic molecules. In this problem, you will look at how the energy levels of the harmonic oscillator relate to the spectrum of carbon monoxide. Part A. There is a strong line in the infrared spectrum of carbon monoxide with a wavelength of 4.61μm. What is the energy E of a photon in this line?
Express your answer in joules to three significant figures.
Part B. It can be shown that this line corresponds to a transition between adjacent energy levels in a harmonic oscillator. If this is true, what is the angular frequency Ï of the oscillator? Use â=1.055Ã10â34Jâs.
Express your answer in inverse seconds to three significant figures.

Part f - example: finding two forces (part i) two dimensional dynamics often involves solving for two unknown quantities in two separate equations describing the total force. the block in (figure 1) has a mass m=10kg and is being pulled by a force f on a table with coefficient of static friction îľs=0.3. four forces act on it: the applied force f (directed î¸=30â above the horizontal). the force of gravity fg=mg (directly down, where g=9.8m/s2). the normal force n (directly up). the force of static friction fs (directly left, opposing any potential motion). if we want to find the size of the force necessary to just barely overcome static friction (in which case fs=îľsn), we use the condition that the sum of the forces in both directions must be 0. using some basic trigonometry, we can write this condition out for the forces in both the horizontal and vertical directions, respectively, as: fcosî¸â’îľsn=0 fsinî¸+nâ’mg=0 in order to find the magnitude of force f, we have to solve a system of two equations with both f and the normal force n unknown. use the methods we have learned to find an expression for f in terms of m, g, î¸, and îľs (no n).
