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. 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.. pp. 562 -567. Mr. Richter. Agenda. Warm-Up. Introduction to Refraction Demo.

What is refraction?. What causes refraction?. What are some examples of refraction of light that show why it is important?. Refraction of Light - Defined. Refraction of light occurs when a light wave moves from a vacuum (or a medium) into another medium (or a vacuum). When a wave changes media, its ____________ changes..
