(10 points) Part 2: Refraction of light. When light changes the medium of transmission, its speed changes. Consequently a ray of light is observed to bend when it enters a different material. This phenomena is called 'refraction', shown in figure 2 below. Alf to glass Light moves 5|0w|y in Glass 9'3\" The ratio of speed of light in a vacuum to speed of light in a material is called 'index of refraction'. Light has maximum speed in a vacuum and consequently, the index of refraction of a material cannot be less than 1. Since the speed of light in air is approximately that in a vacuum, the index of refraction of air is approximately equal to 1. Snell's: law: \"1 Sill Hi = \"3 sin 62 The diagram below shows the meaning of the variables. The diagram below shows the meaning of the variables. n, sin 0, = n2 sin 02 12 2 If material 1 is air, then n1 = 1. We can therefore use Snell's Law, to find n2. We will find the index of refraction of glass, so material 2 will be glass in this experiment. Procedure: 1. Open the simulation using this link: 2. https://phet.colorado.edu/sims/html/bending-lig ht/latest/bending-light en.html 3. Then make sure to click the reset bottom before you start. 4. Set the material to 'glass' 5. Set the laser pointer at any incident angle, then turn it on. 6. Measure 01 and 02 using the protractor. 7. Repeat procedure 2, 3, 4, and 5 for various incident angles. 8. Using Snell's Law, calculate n2 (in this case, index of refraction of glass). Trial 01 02 28. Using Snell's Law, calculate n2 (in this case, index of refraction of glass). Trial 01 92 2 n2 = (sin Percentage 91)/(sin 92) Difference (%) _____ _____ _____ _____ _____ Note: Known index of refraction of glass = 1.52. Conclusion for part 2: Have you verified Snell's Law?
