Spectrophotometry and the Beer-Lambert Law - AP Chem Unit 3, Topic 13

In this video, Mr. Krug shows students how spectrophotometry works and how chemists can use a spectrophotometer to determine the concentration of an unknown substance. He shows how to determine the appropriate wavelength to use in an analysis and how to avoid common mistakes about this topic on exams.

You're welcome. Thanks for your comment!

6:15 I thought the question asked for frequency not wavelength? would you not need to convert it to frequency. aka speed of light/500

[@JeremyKrug]

Very good catch! The question should have read "what wavelength." The control on the spectrophotometer will read wavelength in nanometers.
