Description
The strong points
This device is equipped with a disc with 7 colored sectors, recalling the colors obtained during the decomposition of white light with a prism. Mounted on a motor, the disc rotates at a speed sufficient to demonstrate, as Isaac Newton had shown in his time, that white light is a combination of different colors. The frame fits on stands (to be ordered separately) rod or square format (section 15mm max). Combined with the large diameter of the disc (18cm), this makes the experience visible from afar and ideal for a " teacher " type experience.
