Semi circular Refraction Dish
Semi circular Refraction DishThis open prism can be used in optics experiments to identify the refractive index of different liquids, as the exit angle in relation to the plumb line for the light source can be read at the bottom of the prism.
Note The material is plastic and is therefore not resistant to alkaline or acidic liquids, and it is therefore recommended that the prism be cleaned after use.
