Suppose further that we propose to analyze the solution using an instrument organized as shown below: Light Source Sample Photodetector P o P The light source might be an ordinary light bulb, a flashlight, or the sun. Beer’s Law Page 2 The BEER-LAMBERT LAW Consider This Suppose that we have a solution that absorbs light. Absorbance indicates how much light is absorbed by a sample. If sample A (below) absorbs more light than sample B, which would be smaller, PAorPB? 9/1/ Answer Key 4. P A would be smaller since more power is absorbed by the sample. Beer's Law Page 3 3.
