Watch the first video to help you understand how light can be used as a measurement and analysis tool in chemistry -- pay extra attention to the part about the Beer-Lambert Law.
Watch the second video to get an idea about the next lab we will be doing, Spectrophotometric Determination of Concentration, or Beer's Law. We will be using a spectrophotometer just like this teacher does in our lab, although ours will be larger and older.
