FINAL EXAM - REVIEW PROBLEMS
... Red light from a laser ( 8 = 650 nm) is incident normally (angle of incidence = 2) on a diffraction grating. The first maximum on either side of the center spot occurs at an angle of 23°, as in Fig. (a). Now the angle of incidence is changed to 15°. Calculate 21 and 22 in Fig. (b), the direction of ...

Parallel electric fields in the upward current region of the aurora
... The histogram in Fig. 3共c兲 has a nearly Gaussian shape, indicating that the differences between the integrated electric field and the ion beam energy are somewhat random. There are several possible sources that could contribute to these differences. The values of I have a larger scatter about the ...

... This quantisation of angular momentum fitted in with the predicted energy levels, but left a crucial question unanswered. Why were these particular orbits allowed? In other words, what made this value of angular momentum so special, and why did having angular momentum of nh/2π make the orbit stable? ...

Circular dichroism
Circular dichroism (CD) is dichroism involving circularly polarized light, i.e., the differential absorption of left- and right-handed light. Left-hand circular (LHC) and right-hand circular (RHC) polarized light represent two possible spin angular momentum states for a photon, and so circular dichroism is also referred to as dichroism for spin angular momentum. This phenomenon was discovered by Jean-Baptiste Biot, Augustin Fresnel, and Aimé Cotton in the first half of the 19th century. It is exhibited in the absorption bands of optically active chiral molecules. CD spectroscopy has a wide range of applications in many different fields. Most notably, UV CD is used to investigate the secondary structure of proteins. UV/Vis CD is used to investigate charge-transfer transitions. Near-infrared CD is used to investigate geometric and electronic structure by probing metal d→d transitions. Vibrational circular dichroism, which uses light from the infrared energy region, is used for structural studies of small organic molecules, and most recently proteins and DNA.
