A highly affordable set of 3 laser pointers, perfect for performing experiments involving refraction in the classroom or at home. Light refracts differenly depending on the wavelength of the light. As such, this kit includes a red, green, and blue laser pointer, each of a different wavelength, in order to give a sample of the refractive properties of light at different wavelengths along the whole spectrum of visible light. Shine them through a prism or a diffraction grating and observe the differences! Makes for a great entry-level science fair project or fun classroom activity.
Note: Each laser pointer requires 2 AAA batteries; NOT included
Green: 532nm +/- 10
Blue: 405nm +/- 10
Red: 650nm +/- 10
