1 Lab O3 Snells Law and the Index of Refraction Introduction The bending of a light ray as it passes from air to water is determ ined by Snell s law This law also applies to the bending of light by lenses and to t. 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 pp. 503 – 506, and 525 (24.1).

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. . Intro to Refraction. Take 3 cups from the front, labeled 1,2,3. .

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 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.. Define refractive index.. Demonstrate refraction..
