If the line does not cover the entire vertical range of the Y axis, you should change your Y axis values so the graph covers most of the page and values can be read from the graph with greater precision. Use your graph to answer the following questions. The Absorbance, or Optical Density, of a solution for a particular wavelength of light is given by log(Io/I), where I, is the incident light on a sample and I is the transmitted light. Beer's Law states that the the Optical Density of a substance in solution is directly proportional to its concentration. Not all substances follow Beer's Law, but a calibration graph of Optical Density versus concentration can still be used to measure concentrations of unknown solutions.

Use your graph to answer the following questions. The Absorbance, or Optical Density, of a solution for a particular wavelength of light is given by log(10/I), where I is the incident light on a sample and I is the transmitted light. Beer's Law states that the the Optical Density of a substance in solution is directly proportional to its concentration.
