Spectroscopy

1. The [OII]3727A emission line is actually a line doublet at two wavelengths: 3726.1 A and 3728.8 A. What is the separation of the doublet in velocity units?

2. Can the doublet be resolved by SDSS spectra (ignore additional broadening of the doublet due to motion of the emitting gas)?

There are two absorption lines in the spectral interval: One is located at 7283.02 cm-1 with a line strength of 1.132x10-2 cm-1/(atm cm) and a half width of 0.068 cm-1 (due to pressure broadening) at P0 = 1000 hPa, and another is located at 7283.73 cm-1 with a line strength of 1.71x10-2 cm-1/(atm cm) and a half width of 0.071 cm-1 at the same pressure.

This problem set reviews the basic analytics of cost-effective pollution control. Two firms can reduce emissions of a pollutant at the following marginal costs: MC1 = $12·q1; MC2 = $4·q2, where q1 and q2 are, respectively, the amount of emissions reduced by the first and second firms. Assume that with no control at all, each firm would be emitting 40 units of emissions (for aggregate emissions of 80 tons), and assume that there are no significant transaction costs. 1) Compute...

The wavelengths of spectral lines depends to some extent on the mass of the nucleus. This occurs because the nucleus is not an infinitely heavy mass that remains stationary. In fact, in reality, both the nucleus and the electron orbit about their common center of mass. It can be shown that a system of this type is entirely equivalent to a single object with a mass μμ (called the Reduced Mass) that orbits about the location of the nucleus at...

Two identical cars are traveling in long straight tracks placed side by side. A rope (which can be any length necessary) connects the centers of the two cars (ignore the dimensions of the cars). The positions of the cars change as r1= (2t^3+ 3t^2–10) m and r2= (5t^2–3t–10) m, where t is measured in seconds, for car 1 and car 2 respectively. Time begins being recorded when the rope is perpendicular to the track. The centers of the cars have...

Assume there are two polluting firms in two different cities. In the business-as-usual outcome, Firm #1 would emit 20 units of pollution (e1=20) and Firm #2 would emit 20 units of pollution (e2=20). Additionally, assume the marginal abatement costs for Firm #1 and Firm #2 are given below: MAC1 (x1) = 0.5x1    &    MAC2 (x2) = 2x2 This pollutant is known to cause adverse health effects when in high concentrations. Since the firms are in different cities, assume the marginal social benefit...

1. Light traveling in air (index of refraction 1.00) falls onto a thin plastic film (index of refraction 1.30) of unknown thickness that covers glass (index of refraction 1.50). What minimum non-zero thickness is needed such that wavelengths of 650 nm in air are bright in the reflection? 2. You observe two point sources of light that are spaced 10 cm apart which are each emitting light of wavelength of 590 nm. If the diameter of your pupil is 2...
