Activity 6 Directions: Solve for the given problems. Show your complete solutions. Express your final answers into 3 significant figures. Write your answers on another sheet of paper. 1. The refractive index for a diamond for red light is 2.41 while that for blue light is 2.45. Their wavelengths are 650 nm and 430 nm, respectively. If whitelight enters the diamond at 250, what are the angles of refraction of these colors? 2. The refractive index of crown glass for red light is 1.51 and 1.53 for violet light. Find the speed of red light and speed of violet light in crown glass. 3. If a light ray in fabulite enters air, find the largest angle of incidence that the ray can form with the normal for it not to be reflected back into the fabulite. (nfabulite = 2.41)
