This apparatus helps students easily to study reflection and refraction. The rotating base provides a high degree of accuracy when making measurements as well as provides an easy way to change angles without disturbing light source or the object the light is being shown upon. The acrylic semi-circle can be filled with different mediums for measuring the Index of Refraction. A light source is mounted on the base with single, double, triple and wide slit attachments, two metal shields for blocking light, an acrylic lens for focusing the beam of light. Teacher instructions are available to help students use Snell's Law to determine the critical angle of a fluid, to find the Index of Refraction, and to discover the Law of Reflection. Requires a 12V DC power supply for the light source, not included.
