PPT-12.1 What is Refraction?

What is Refraction In a vacuum air light travels in straight lines But what happens when light travels from one material into another Like for example from air to water What Happens When Light hits a Medium. Principles When light passes at an angle from one medium to another it undergoes refraction The angle of incidence and the angle of refraction are measured relative to the normal a line perpendicular to the surface If the indices of the two media 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.. What has happened in each example and why?. I think this is called.... It happens when.... It happens because.... The air is.... The water is.... The light usually. travels...but when it hits water.... PHYS . 132-. 002: . Wednesday, May . 11 . @ 10-11:50 am.

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.. Reflection. When a wave reaches a boundary between two media, usually some or all of the wave bounces back into the first medium.. A metal surface is rigid to light waves that shine upon it. . Light . 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.. Give examples of refraction in nature.. WITH DISPERSION. CSS552 – Topics in Rendering. Winter . 2011. Final Project by:. Kohei Ueda. Shivani Srikanteshwara. Mary Ann Chiramattel Kunjachan. What we will present today …. Introduction to dispersion. LIGHT. Light carries . energy. and . power.. Light . is a form of . energy. that travels.. The . intensity. . of light is the amount of energy per . second. falling on a surface.. Most light sources distribute their light . Of light. By: Ahmed. Definitions. Luminous . objects . – . generate their own light (the sun). Illuminated. objects – reflect light (the moon). Definitions. Line . of Sight . – a line from an object or image to your eyes (light from the object travels along this line to your eyes). light bends or refracts when it moves from one medium to another. the light bends because it changes speed. if light slows down it bends toward the normal. if light speeds up it bends away from the normal. o. . What is the angle of incidence in glass?. Problem 1. Light travels from crown glass (n=1.52) into air (n=1.00). The angle of refraction in air is 60. o. . What is the angle of incidence in glass?.
