A precision crafted right angle acrylic prism includes instructions to learn secrets of prismatic effects – you can even make a periscope with the Right Angle Prism. Instructions are included.
Since the first moment that a rainbow appeared in the sky people have been fascinated with prismatic effects. Sir Issac Newton probably made the first prism discoveries while in college attempting to solve the problems of early telescope lens making.
Light travels more slowly through the prism than through air. When a beam of light enters the prism at an angle, this slowing of the light bends (refracts) the light. How much it bends depends on the wavelength of the light. Since white light is made up of all the colors, each with a different wavelength, the colors are dispersed into a rainbow; with the longest wavelength, red, bent the least and the shortest wavelength, indigo, is bent the most.
