ap chemistry - beer-lambert law & spectroscopy
originally streamed in 2020 with Jacob JeffriesStudentcurriculum note
The video description references 'Unit 4' for Beer-Lambert Law, but in the current AP Chemistry course this content is covered in Unit 3 (Intermolecular Forces and Properties). The current topic tags also incorrectly list the Photoelectric Effect (3.12), which is not covered in this video.
