The optical water tank with laser allows students to measure and study refraction of light. The angles of incident and refractive rays are easy to see when using the built-in laser. The water that is added to the tank provides a surface for reflecting the laser light. The laser light can be positioned and fixed at any point around the 6-inch graduated circle. The 4 prisms and 2 mirrors are included in the kit and can be mounted in the center of the tank.
