Laser Reflection And Refraction Tank

Laser Reflection and Refraction Tank demonstrates the principle of reflection and refraction. The clear circular acrylic tank has a circular scale graduated on the white base of the tank, making it easy to measure angles. Adjust the pivot-arm mounted laser to any angle along its full 360° range and measure the angle of reflection or refraction. Rotate the laser and observe first a reflected ray, then both a reflected and refracted ray, and finally just a refracted ray. Leveling screws on the tank’s base make leveling quick and easy. The laser is attached to the pivot-arm by a magnet and can be removed for use in other experiments. Instructions included.
