Laser Beam Refraction - Demonstration Model

The model clearly demonstrates the refraction of a laser beam as it passes from one medium into another (here: water) and the phenomenon of reflection. It consists of a transparent front panel and a cylindrical water reservoir with a 360-degree scale on the rear wall, made of plastic with a diameter of 16 cm, and a movable arm with a laser activated by a button. The entire assembly rests on a base.
