Hello, all. I have a general question related to something I read in a book right now. Not taking a course so I have no professor to ask, so I come to you all! To speed things up, I have this image I took from the book: My question is if the analyzer's polarizing axis was an arbitrary theta from the vertical, then E perpendicular would still lie on it's axis, right? As long as it wasn't perpendicular. I'm having a hard time visualizing this for some reason.
