2. Discovering Optics Concepts Through Diffraction
Outlining one of its optics activities that reveals concepts in diffraction of light, NASA’s “Diffraction of Light by Very Small Apertures” shows students how to examine the ways in which light-ray direction shifts when light passes through different screens.
Unsure of what aperture means? The smart folks at NASA have you covered right in the document. The only thing you’ll need to track down are some diffraction screens to make this lesson plan enlightening for students.
