Ray Optics Tabletop Kit: explore how lenses work with this inexpensive experimentation kit featuring three parallel laser beams and 2-D versions of lenses and other shapes that use refraction to alter the direction of light. Here a doubly concave lens interacts with the beams from a doubly convex lens. ➡️ Follow the link in my profile for info on where to get this very affordable demo kit and other amazing items featured here on @physicsfun #optics #lens #convexlens #internalreflection #refracti

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
