Unformatted text preview: Lab Experiment #4 Interaction of Light with Matter: Beers Law Ryan Henry Section 523 Lab Partner: Charlotte McCoy Summary: The purpose of this experiment was to determine the effects of path length, concentration, and color on the amount of light transmitted through a solution and develop a mathematical formula for the relationship among these variables. In this experiment, we used a laser, light detector, and LoggerPro software. In the first part of the experiment, we filled 5 cuvettes with 0.03 M copper sulfate solution and placed them in between the laser and light detector one at a time and recorded the light intensity after each one was added. In the second part, we started with a 0.25 M copper sulfate solution and put it in between the laser and light detector and measured the light intensity. We then started diluting the solution by adding 1mL of water at a time until we reached a total of 4mL of water and recorded the light intensity each time. In the final part of the experiment, we simply filled a cuvette with a solution of red food coloring and...
