Fill these semicircular cells with different liquids to observe their refractive properties. Great for showing total internal reflection! Measure angles with the printed protractor.
Great for showing total internal reflection!
Fill these semicircular cells with different liquids to observe their refractive properties. To help measure the angles, there is a printer "protractor" on the base of the cup that is marked with degrees along the curved edge.
Locate the object and its image and use Snell's Law to determine the index of refraction.
