This highly interdisciplinary experiment will expose the students to the wave nature of light and the concept of polarization. The experimenters will use a tabletop laser as a light source and will use polarizers to control the generation and transmission of polarized light. Furthermore, students will determine the optical activity of a chiral molecule. The experiment will also engage the students in an exercise whereby they will be asked to describe what is meant by “optimum” measurements.
