Reflection and Refraction of a Cyan Laser Pointer: an affordable laser pointer with a color that’s pretty new on the market- 488nm producing a beautiful hue of blue. The beam is made brightly visible as internal reflection constrains most of the laser light to propagate along the interior of this block of acrylic (similar to the physics of fiber optics). ➡️ Follow the link in my profile for info on where to get a cyan laser and clear demonstration block like these and other amazing items feature

Aurora Laser Projector: red, green, and blue laser elements are refracted through a rotating optical element with lumpy surface features which create this amazing aurora/nebula effect. When light rays refract through a curved surface they concentrate into bright patches called caustics, often with cusp singularities (sharp points) and intricate threads of shadow. ➡ Follow the link in my profile for info on where to get this and other amazing items featured here on @physicsfun #physics #physicsto
