EISCO Equilateral Acrylic Prisms, Set of 3 – 25, 50, 100mm Lengths
This set is of highly polished acrylic equilateral prisms — 25mm sides and lengths of 25, 50 and 100mm.
Prisms will create a nice rainbow (even in room light) by using the simple LED light of a smart phone (such as an iPhone). User will need to create a small slit in a black piece of paper and use that slit in front of the LED which will create a light ray. The prisms will then refract the white light and create a nice rainbow on a target away from the prism. The farther away you move the target the bigger the rainbow gets and the more distinct colors the user can see. A great tool for teaching refraction and science education, or for just having fun!
