PhysicsQuest 2009
Waves
Learn about light waves and wavelengths by manipulating laser beam patterns, polarizing light rays, using colors to increase intensity, and using laser beams to take measurements.
Middle school lesson plans for waves

How can a laser be used to measure the width of a human hair?
In the experiment, students will use filters of color to gather data and explain “What colors of light cause a glow in the dark square to glow?"
Can you find the properties of the light waves coming out of your laser using the pattern formed when you shine the laser through cloth?
