1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution (3) I haven't been able to start this one at all. (6) I got part a (+45ยบ P-state). I tried to do b and I got [1+i, -i+1] which isn't a polarization state, so I'm not sure what to do with c or if there is some way I can simplify it. (7) Once again, I got part a. It's of the form E=[tex]E_{0}[/tex][[tex]\widehat{i}[/tex]cos(kz-wt)+[tex]\widehat{j}[/tex]sin(kz-wt)] Does the cosine term drop out from the initial conditions? For b, I'm not sure how to get the magnetic field equation. I know [tex]\overline{B}[/tex]=([tex]\overline{K}[/tex][tex]\times[/tex][tex]\overline{E}[/tex])/[tex]\omega[/tex] But, I'm not sure how that helps me Any help would be greatly appreciated!
3, sounds like it is describing a kepler telescope - a common design for a beam expander. The two positive lenses are separated by the sum of their focal lengths. The magnification is the ratio of the focal lengths. A simple sketch shows you how it works.
What school do you go to, that paper and font, its exactly the same, is there some standard I don't know about?
