Curated OER
Light and Laser
Twelfth graders investigate the refractive index of water. In this physics lesson, 12th graders explain the operation of laser. They write a lab report about the activity.
Curated OER
Frozen Film
Students discover how light reflects off surfaces. In this hands-on demonstration, students examine how variations in color are produced by light interference.
Curated OER
Frozen Film
Students are introduced to the topic of light interference through this hands-on activity. They observe how light reflects off two surfaces and then meets to form an interesting variation of color on a film surface.
