Refraction (bending light) Refraction is when light bends as it passes from one medium into another. When light traveling through air passes into the glass.

Presentation transcript:

Warm Up 1) In what two ways can refraction be useful? 2) Where have you seen lenses get used?

Goals Discuss Total Internal Reflection Discuss the Ray diagram rules for Lenses

Lens Ray Diagram Rules 1) Parallel – focal point A parallel ray will get refracted through a focal point 2) Focal Point – Parallel A ray aimed through a focal point will come out parallel 3) Center of the lens A line through the center of the lens will NOT bend YOU ONLY NEED TO USE 2 of THESE AT A TIME
