Interference and Diffraction in Modern Technology: A New Approach for an Introductory Physics Laboratory Experiment

A classic undergraduate introductory experiment is to measure the diffraction and interference pattern from single and double slits to determine slit width and separation. Studies show that Course-based Undergraduate Research Experiences (CUREs) can make science more inclusive when offered at the undergraduate level. Additionally, CUREs help students to understand the scientific research process. We have redesigned our diffraction and interference lab to incorporate these best-teaching practices to enhance the students’ learning experience.
