Simple Device for Spectroscopy Laboratory Exercises

Undergraduate physics laboratory exercises are very important in shaping students' attitude to science, especially for future teachers. Recently, it is necessary to look for ways to easily create large quantities of experimental sets, not only for institutional use, but also for sets that can be produced in large quantities and distributed for use in distance learning. In this paper, we briefly describe the various ways to support the teaching of wave optics, and then describe one of the possible methods for performing undergraduate spectroscopic measurements using a 3D printed spectroscope and light source.
