Scientific tool for demonstrating and assessing the refraction of light, Italy 1920.

Italy beginning of 1900.

Scientific tool for demonstrating and assessing the refraction of light. Constructed in boxed metal with a square section, it consists of a horizontal tube that bends a few grids in the last section. Above the painted indications for the evaluation of the phenomenon. The base is made of turned and fruitwood. At the end of the short part, in the center of the lower side, a lamina of considerable length is extractable at the end of which a candle is inserted. Water held by the glass is integrated at the elbow, creating a natural lens. In a dark environment, by lighting the candle and moving it for and against the tube at the opposite exit the light refracts variously. Italy circa 1920.
