Interference and diffraction laser kit

We designed a low cost modular assembly using an inexpensive laser pointer to study interference and diffraction in introductory physics. This was in response to our desire for the students to have a hands-on laboratory experience during the COVID-19 lock-down.

Post-Printing

We used 0.015 diameter music wire from K & S metals for the wire slide. Wire was cut to length and a drop of super glue in each of the two small wells was used to secure the wire to the slide.
