PPT-Refraction of Light

CHAPTER 7 What is Refraction What is Optical Density The Laws of Refraction The Refractive index Angle of Incidence Refraction Total Internal Reflection Refraction is the change in direction of light when it passes from one medium to another. pp. 503 – 506, and 525 (24.1). Mr. Richter. Agenda. Warm-Up. Notes:. The Speed of Light. Index of Refraction. Angle of Refraction. Total Internal Reflection. Dispersion . Objectives: We Will Be Able To…. Unit 8. How we use light to see.. To the physicist, the colors of things are not in the substances of the things themselves.. Color is in the eye of the beholder and is provoked by the frequencies of light emitted or reflected by things.. Mr. . . Dvorsky. SNC2D1. Review of last chapter. From the last chapter, we know how light behaves when it travels in space or in the air – i.e. it travels in a straight line.. When light strikes a plane mirror, the angle of incidence = the angle of reflection. . Intro to Refraction. Take 3 cups from the front, labeled 1,2,3. . Observe each straw through the side of the cup as you slowly turn the cup. . DO NOT STIR THE CONTENTS!. Write down your observations. . Presented by: Vandana Bathla & Eric Williams. Light Refraction.
