Optical Glass Triangular Prism, 2 Pack 1.97 Inch Crystal Rainbow Maker for Photography Science Experiments Physics Teaching Light Spectrum

Use the prism to create a rainbow! How does a prism create a rainbow When light moves from air into the glass of the prism, light refraction occurs. The design of the prism causes the light to change direction. A ray of light is made up of many wavelengths of light. Each wavelength passes through the prism with different resistance than the other light waves. The different wavelengths normally travel together but get dispersed passing through a prism and we can see them separately as a rainbow. Quality Craftsmanship Our prisms are made with optical glass. They are checked for clarity and imperfections during the manufacturing process. Our prisms are hand sanded and polished to our specific size requirements to maintain consistency and quality. How to use vShow your kids a rainbow with light refraction Turn on the flashlight and hold the prism in the light. Continue to twist and turn your prism in the light source until a corner of the triangle falls into the light beam. Light should then refract through the prism and create a rainbow on your background. vUse your prism to create unique photography effects. Professional photographers with a top of the line camera and amateurs using cell phones for pictures can both use this device. You can achieve all sorts of different effects using our prisms with time and practice.
