Refraction and Total Internal Reflection
Refraction and Total Internal Reflection

Students will be able to observe that refraction (bending) always takes place at the interface between two different transparent materials and that the angle of refraction in plastic is smaller than the angle of incidence in air. The light is...

Refraction: Converging Lenses
Refraction: Converging Lenses

Students investigate images formed by converging lenses using the Light Box & Optical Set, and discover the Focal Point. Download Teacher Notes and Student Worksheets Required Equipment

Reflection and Refraction
Reflection and Refraction

The Law of Reflection states that the angle of incidence is equal to the angle of reflection. Students will use ray tracing to predict the location and image characteristics for flat and curved mirrors. Students will use ray tracing to...

Lab #29.12   Light: Trapping the Light Fantastic
Lab #29.12 Light: Trapping the Light Fantastic

PurposeIn this activity, students will investigate the behavior of light as it passes from one transparent material to another. DiscussionWhen light passes from one transparent material to another, it undergoes refraction. If the light crosses the boundary between the materials...

Reflection & Refraction

One day in my classroom…"My students were amazed by examples of colorful fiber optics but didn't understand how the light goes from one end to the other; even when bent. After testing various angles of laser light through water and...
