Pfund's Method

We can measure the index of refraction of a material by observing the angle of total internal reflection. Pfund's method is a way of measuring that angle accurately.

Equipment built by Eric Ayars and Jaydie Lee during the summer of '18. Acrylic and glass have been tested and work great. Ice works also. Jello is still an open question.
