35: Chapter Interference Problem 1 The speed of yellow light (from a sodium lamp) in a certain liquid is measured to be 1.92 108 m/s. What is the index of refraction of this liquid for the light? Answer 1.56 Solution The index of refraction is equal to the speed of light in vacuum divided by the speed of light in the liquid: m c s = 1.56 n= = vl 1.92 10 8 m s 3 10 8 Problem 3 How much faster, in meters per...
