Critical Angle
When does total reflection begin? Light usually travels in a straight line. What happens when it encounters a boundary surface? Depending on the angle of…
Disappearing Glass Rods
Brought before your eyes: Optical density. Similar to how a drinking straw appears bent in a glass – here is another way to illustrate the phenomenon of…
Double Refraction in Calcite Crystals
Viewed through Iceland spar: The lettering appears doubled. Light entering this Iceland spar calcite crystal is split into two beams with opposite…
Droplet Fountain
Wave patterns. A single drop falls. In the fountain, a wave pattern appears. How does it develop towards the edge? A strike on the button at the edge…
Fresnel Lens
Thin lens, big effect. When two visitors look at each other through this large Fresnel lens, they see the other person with an enormous upper body. Since…
Glass Bead Rainbow
Refracting light, reflecting light. Tiny glass beads illuminated by a flashlight: a rainbow appears! They act like prisms, these glass beads. They split the…
Light Island
Reflex – simply play with light. Direct light, mix light colors, experiment with the transparency of filters and materials, and explore refraction: freely…
Make the Invisible Visible
Convection made clear and observable. When water is heated, it expands. It becomes lighter and rises. In the less heated water, it creates swirls. The heat…
Total Internal Reflection
Trapped light. A tip for the dear citizens of Schilda: here’s how you could have brought light into the windowless town hall! The method is based on a…
