How Can I Solve These Optics Practice Test Problems?

AI Thread Summary
The discussion revolves around solving optics practice test problems, with users sharing their attempts and challenges. One participant successfully completed part a of a problem but struggled with parts b and c, particularly with polarization states and simplifying equations. Another user noted the form of the electric field equation and questioned the relevance of the cosine term in initial conditions, while seeking guidance on deriving the magnetic field equation. Additionally, there was a side conversation about the standardization of paper and font used in academic submissions. Overall, participants are looking for collaborative help in understanding optics concepts and problem-solving techniques.

Homework Equations





The Attempt at a Solution



(3) I haven't been able to start this one at all.

(6) I got part a (+45º 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=E_{0}[\widehat{i}cos(kz-wt)+\widehat{j}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 \overline{B}=(\overline{K}\times\overline{E})/\omega
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?

Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'
(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
