PPT-Chapter 16.4 – Refraction, Lenses, and Prisms

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.

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. . 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.... 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. Refraction of Light. EM lesson 8. Convex . (converging) Lens. Thicker in the center than at the edges. Have positive focal lengths . Converge. . parallel rays of light that pass through them. Rules for convex lenses. 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.. 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. 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.. is the bending of light as it passes from one medium into another.. refraction. N. q. w. q. A. Note: the angle of incidence . q. A. . in air and the angle of refraction . q. A. . in water are each measured with the normal . Vocabulary . Refraction-. . the bending of light as it passes from one material into another.. Prism-. . a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms. 10-7 Volume of Prisms Course 1 Warm Up Lesson Presentation Problem of the Day Warm Up Find the area of each figure.
