Introduction: Today’s laboratory experiment consisted in studying the concept of  refraction. Last week we studied the case when light strikes a surface and bounces  (reflects) back. This week we are studying refraction, which is the case when the light  enters a medium and travels through this medium. The light changes speed as it travels  in a different medium and therefore is bent from its original path. Snell’s Law gives the  relationship between the two angles formed by the normal of the surface, and the two  mediums indicated by the index of refraction (n). In this experiment we first studied  Snell’s law by experimentally measuring the index of refraction and how the angles  changed as the light entered a different medium. Then we studied the special case of

Unformatted text preview: Snell’s law which is when total internal reflection. And finally we studied the behavior of light as it moves through a medium shaped as a converging or diverging mirror. Analysis is in following pages. Conclusion: In this experiment I learned how to apply Snell’s Law to find the index of refraction or the angle of refraction. By doing this I was able to understand how light rays behave as the move from one medium to another, and the relationship between the angle at which it strikes the surface of the second medium and the angle at which it is refracted. Lastly, I also learned about thick lenses and the effect the index of refraction can have towards the focal length of the lens. Due to the bending of the rays of light through the medium of the lens, the focal length may increase or decrease....
