Diffraction
Kindle knowledge of how light travels by using this activity in your physical science curriculum. By setting up a candle flame or flashlight bulb and viewing it through a slit, observers of light see evidence of its wave characteristic....
Cornell University
Diffraction Demystified
Study diffraction patterns using CDs and DVDs! Scholars measure the diffraction patterns of a light wave as it hits a CD or DVD. Using the information, they can measure the distance between the tracks.
Cornell University
Light Waves: Grades 9-12
Explore the behavior of light waves with a lab activity. Scholars build new vocabulary through experimentation and observation. Using different mediums, they model reflection, refraction, transmission, diffusion, and scattering of light.
Cornell University
Building Spectroscope
Given specific materials, scholars follow a set of instructions to build and calibrate their very own spectroscopes. After construction, they test the scope for accuracy and make modifications where necessary.
