PPT-Refraction of Light

Emmetropia and the Ametropias Scott P Drexler OD University of Pittsburgh School of Medicine AKA Shape is Power Light is a Wave The direction and quality of that wave is changed as the wave transfers 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…. RAY OPTICS -I Refraction of Light: Refraction is the phenomenon of change in the path of light as it travels from one medium to another (when the ray of light is incident obliquely). It can also be de 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.. When light travels from one material to another it usually changes direction. The bending of light that occurs at the borderline of two materials is called . refraction. Geometrical concepts:. -incident ray. pp. 562 -567. Mr. Richter. Agenda. Warm-Up.

Presented by: Vandana Bathla & Eric Williams. Light Refraction. Have you ever wondered why it appears we see puddles of water on a highway on a hot summer day?. What you are seeing is not really water, but a mirage.. 1. Put the penny in the . cup. . Look at the penny, then walk backwards . until just . after you can't see the penny anymore.. 2. It's very important that you can't see the penny. Without that, the magic . Transparent substances refract light. It’s not magic… it’s science!. How light Refracts. Refraction is due to changes in the speed of light.. In space, light travels at 300 000 km/s. Space is a vacuum, and there are no particles to get in the way of light and slow it down.. Define refractive index.. Demonstrate refraction.. State the Laws of Refraction.. Solve problems about refraction.. HL: Solve problems about refractive index in terms of relative speeds..
