AI Thread Summary
The discussion centers on the feasibility of converting a circularly polarized plane wave in air into a linearly polarized wave through reflection from a lossless nonmagnetic dielectric. The researcher’s claim is examined by calculating the reflected wave and determining if such a conversion is possible at normal incidence. The analysis reveals that the conversion is not achievable under the given conditions, as the necessary refractive index does not exist for this transformation to occur. The conclusion emphasizes that the properties of circular and linear polarization do not allow for this conversion through simple reflection. Therefore, the researcher’s claim is incorrect based on the calculations provided.

Homework Statement



2) A researcher claims that she can convert a circularly polarized plane wave in air into a linearly polarized one by simply reflecting it from a suitably chosen lossless nonmagnetic dieletric. Assume the dielectric she will use has refractive index n. Is this feat possible for normail incidence, as she claims? Calculate the reflected wave to justify your answer. If she is right, is there a mininum value of n for this to work? If she is wrong; briefly explain why, based on your calculation.

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...

Hi, I'm stuck at this question, please help. Attempt to the Conducting Sphere and Dipole Problem (a) Electric Field and Potential at O due to Induced Charges $$V_O = 0$$ This potential is the sum of the potentials due to the real charges (##+q, -q##) and the induced charges on the sphere. $$V_O = V_{\text{real}} + V_{\text{induced}} = 0$$ - Electric Field at O, ##\vec{E}_O##: Since point O is inside a conductor in electrostatic equilibrium, the electric field there must be zero...
