Document Summary

Sun two males the light (more light more male) why sun people are the best leaders? (look at weekly qs) most male, attracted to male things. Moon male and female sun reflects little light. Body sex orientation three sex model and its employment by later thinkers (dionian is considered standard; they don"t require explanation because opposite sex attraction is the standard) Uranian anyone who isn"t heterosexual everyone who requires special explanations. Same sex attraction seeds of who we are might not match the gender of your body. Its your germ that is attracted to the opposite sex; if we males are attracted to each other, one of them have a female germ. [m germ] [f germ] m1 senses m2"s f germ. Sexual orientation development or innate? development: grow into; Freud: something about early childhood development innate: something that"s been there; there from birth; scientific view. Explanations for inuit decision to raise children the opposite sex.

The “resolving power” of any optical system is limited by thewave-like property of light–and photons–through diffraction orinterference. This is often described by the “Rayleigh criterion”which states that the minimum angular separation dR for two objectsto be resolved by an optical system having a circular aperture ofdiameter D using light of wavelength ? is dR = 1.22 ?/D. What isthe minimum distance d between two points on the earth’s surfacecan be resolved by the GeoEye optical system discussed in theprevious question at anominal wavelength of ? = 550 nm?

(Refer this question as Previous question)
Often, sodium vapor lamps are used to illuminate large outdoorareas because they
mainly radiate at two nearly equal wavelengths, the sodium yellow“D” lines ? =589 nm. Suppose a 1 kW lamp is 50% efficient atproducing photons at this wave-length. How many such photons areproduced per second? Assuming the photons radiate isotropicallyfrom the lamb, how may photons enter the pupil of one of your eyesif you are standing 100 m from the lamp? Assume the pupil to have aradius of 1 mm.
Now suppose the“GeoEye-1” satellite, a supplier of images forGoogle-Earth, is
observing the area around the lamp at night. Assume the satellitecollects all the
photons hitting a 1 m diameter circular aperture formed by itsimaging system when
it is looking straight down from its orbital altitude of 681 km.How many photons
per second are collected from the lamp by GeoEye?

**Explain in details please**

Suppose we have reason to suspect that a certain quantum objecthasonly three quantum states. When we excite a collection ofsuchobjects we observe that they emit electromagnetic radiationofthree different energies: 0.9 eV (infrared), 1.9 eV (visible),and 2.8 eV (visible).

(a) Draw a possible energy-level diagram for one of thequantumobjects, which has three bound states. On the diagram,indicate thetransitions corresponding to the emitted photons, andcheck thatthe possible transitions produce the observed photons andnoothers. When you are sure that your energy-level diagramisconsistent with the observed photon energies, enter the energiesofeach level (K+U, which is negative). EnterALLlevels before submitting; all of the energies must be correctto beproperly scored. The energy K+U of theground state is -4eV.
eV = energy of highest level(2nd excited state)
eV = energy of next highestlevel (1st excited state)
-4 eV = energy of groundstate

(b) The material is now cooled down to a very low temperature,andthe photon detector stops detecting photon emissions. Next abeamof light with a continuous range of energies from infraredthroughultraviolet shines on the material, and the photondetectorobserves the beam of light after it passes through thematerial.What photon energies in this beam of light are observed tobesignificantly reduced in intensity ("dark absorptionlines")?
Energy of highest-energy dark line: eV
Energy of lowest-energy dark line: eV

(c) There exists another possible set of energy levels fortheseobjects which produces the same photon emission spectrum. Onanalternative energy-level diagram, different from the one you drew inpart(a), indicate the transitions corresponding to theemittedphotons, and check that the possible transitions producetheobserved photons and no others. When you are sure thatyouralternative energy-level diagram is consistent with theobservedphoton energies, enter the energies of each level(K+U,which is negative). Enter ALL levelsbeforesubmitting; all of the energies must be correct to beproperlyscored.
eV = energy of highest level(2nd excited state)
eV = energy of next highestlevel (1st excited state)
-4 eV = energy of groundstate

(d) For your second proposed energy-level scheme, whatphotonenergies would be observed to be significantly reduced inintensityin an absorption experiment ("dark absorption lines")?(Given thedifferences from part (b), you can see that anabsorptionmeasurement can be used to tell which of your twoenergy-levelschemes is correct.)
Energy of highest-energy dark line: eV
Energy of lowest-energy dark line: eV
