Mr. Richter. Agenda. Warm-Up. Introduction to Refraction Demo. Reminder: Quarter 3 Ends Friday. Notes:. Refraction. Index of Refraction. Why Light Bends. Refracted Images. Snell’s Law. 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. . 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. 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.. Refraction occurs at a boundary. The speed of light must change at the boundary. The angle of the light ray is measured from the normal, as was the case with reflection. If the speed slows across the boundary, the refracted angle will be smaller – the light ray will bend toward the normal.. What interactions can waves undergo?. Name: ________________ Date: ___________. . 6.P.1.1 Waves: Forces and Motion. EQ: What interactions can waves undergo?. Reflection... head your notes like this!. The Diary of a Young Girl .
