AI Thread Summary
Coronal holes and sunspots are distinct solar phenomena. Coronal holes appear as darker areas in X-ray images and are associated with lower density and temperature in the sun's corona, contributing to solar wind. Sunspots, on the other hand, result from reduced convection in the photosphere due to heightened magnetic activity. While there is some correlation between the two, they represent different processes on the sun. Understanding these differences is crucial for studying solar activity and its effects on space weather.

Coronal holes are the darker spots when viewed on a x ray picture, I've been doing some reading and it says on many websites that coronal holes create CME but it doesn't say anything about coronal mass ejection and sunspots

Sunspots are related to lower activity of convection in the sun's photosphere due to an increased magnetic activity. Coronal holes are areas in the sun's corona which are colder and has lower density.

Coronal holes are related to solar wind, and there is some correlation between coronal holes and sun spots, but they are not the same phenomena.

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...
