#5 and Prism on Critical Angle & Total Internal Reflection worksheet

In class Practice pg. 509 #74, 75, 76, 78, 79

74. Just like your warm-up question. You have two calculations using Snell's Law with two slightly different indices of refraction. Both angles of refraction should be close to 12 degrees.

75. Both parts should be close to 2x10^8 m/s.

76. First you need to use that information to solve for the index of refraction of the "special glass." Assume its trying to get into air. (~1.5) Then use that index of refraction with water to find what the critical angle will be. (<61)

78.Refer to the figure! (a) Given the index of refraction for air and for the prism and the angle of sincidenc you can use Snell's to calculate the angle of refraction. Since the light is going from a less dense to a more dense material you should be able to guess if the angle or refraction is smaller than or greater than the incident angle. (<30) (b) You've taken geometry. (c) Givin this new angle of incidence and the same indices of refraction, determine the angle of refraction as it leaves the prism. Since the light is going from a more dense to a less dense material you should be able to guess if the angle or refraction is smaller than or greater than the incident angle. (>50)

79.Given the speed of light in plastic and knowing the speed of light in a vacuum you can determine the index of refraction. With that information and the angle of incidence you can determine the angle of refraction. (Assume its exited into air) (10>)
