9. List the 5 building blocks of a modern illumination apparatus.
10. Köhler illumination, put in the correct order: [the steps of Köhler illumination shuffled]

I also attatched a screenshot of the questions and the PDF i learned with. I made the PDF myself, but I got lazy in the last chapter and didn't complete it, sorry for that. In addition took a PDF with older questions and tried answering them (the greyed out parts weren't part of the subject matter in WS20)
