Light Crystal Prism 2.5
Refraction through Prism is easily demonstrated with this 2.5" Crystal Prism. Natural sunlight is refracted into a full spectrum of colors - Red, Orange, Yellow, Green, Blue, Indigo and Violet. ROY G BIV is the mnemonic I learned to remember the correct colors in the correct order. Prism is highly polished acrylic and must be handled with care. Made in USA. Ages 6 & Up.
