Reflection and Refraction
Learn about reflection and refraction via lasers in water.
Variable Index of Refraction
A sugar-water solution is used to create a liquid with a variable index of refraction. Participants learn about solutions, gradients, and refraction.
Polarization of Light
This demonstration explains transverse waves and some surprising properties of polarizers.
Marshmallows & the Speed of Light
This workshop uses marshmallows to teach participants about waves and to calculate the speed of light.
Reflection & Refraction
This demonstration presents viewers with an example of reflection and refraction and describes difference between the two.
Light Fountain
This demonstration shows how light changes paths when travelling through different materials. Snell’s Law and the critical angle are explored using lasers and water.
Hair Diffraction
Participants use a hair to show how light can interfere to produce a diffraction pattern.
