Bent Laser Light
Diffraction patterns: when light is deflected. When light encounters a fine structure (like a hair), it is deflected by it. Here, laser light is deflected as…
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…
Experiments with polarized Light
Playing with light and colors. Light is a wave – and its oscillations vibrate in different directions. With polarization filters and everyday objects, this…
Favourite Uncle
Polarization + collage = Polage®. "Prometheus" is a unique work of art, layered on multiple levels. A picture that continuously changes, surprising and…
Light Spiral
The light spins! Polarized white light enters a stationary cylinder filled with a sugar solution. The sugar molecules cause a left-handed rotation of the…
Newton Rings
Light cancels out light. A simple glass plate under normal light. Under the orange, monochromatic light of a sodium-vapor lamp, a bizarre landscape is…
Particle or Wave
Particle or wave? Both are correct. As an electromagnetic wave, light spreads out with all the typical characteristics of a wave. At the same time, it behaves…
Soap Bubble Basin
Loooong bubbles For kids big and small: form soap bubbles several meters long. Sometimes, a bubble stretches into a tube large enough for a child to fit…
Soap Film Painting
A film with a bulge. Beautiful, the colors that appear when the wide, tall soap film forms! Its colorful patterns are constantly changing. They clearly…
Spectra
Elements and their colors. Distinguishing individual hues from a color impression: it’s as challenging as identifying individual instruments in an orchestra.…
The Faraday Effect
Magnetic field affects polarization direction. Here, light is polarized by a filter and then sent through a liquid. On the other side, another polarizing…
The Kiss II
Moving and moving: multiplex hologram. Also known as a stereogram or integral hologram, “The Kiss” is the most famous multiplex hologram, a development of the…
Unwanted Light Reflections
Unwanted reflections – a simple trick. Photographers are familiar with this: light reflections on glass or water surfaces – and they can be disruptive. A…
Wave Patterns
Waves on the surface of a thin layer of water become clearly visible with a suitable projection. A vibrating beam produces waves with straight-line crests.…
What is Polarization?
Light and oscillations. Normal, unpolarized light is a mixture of light waves with different oscillation directions. When all light waves have the same…
CD Spectroscope
Make a truth teller for light. Turn an old CD into a spectroscope to analyze light—you may be surprised by what you see. Try pointing your CD spectroscope at…
Diffraction
Light can bend around edges. Light bends when it passes around an edge or through a slit. This bending is called diffraction. You can easily demonstrate…
Glue Stick Sunset
Why is the sky blue? That's a sticky question. Model the scattering of light by the atmosphere—which makes our sky appear blue and our sunsets red—by shining a…
Moire Patterns
Imperfect alignment can lead to interesting patterns. When you look through one chain-link fence at another, you sometimes see a pattern of light and dark…
Have you ever seen an atom? – Atomic dimensions
Physics lessons in mainstream school education were extremely limited during the 20th century – especially when it came to expensive and complex experiments.…
