5. The figure below shows a slab made of three different materials X, Y and Z having refractive indices nx, ny, and n: respectively. The slab is immersed in water (n=1.333) and the light is incident upon its bottom surface. water Y water a. Rank the materials according to the refractive index of the materials, greatest firs b. Rank tne materials according to the speed of light in the material, greatest/fastest first. c. Discuss what would happen to the angle y if material X and Y are swapped. d. If a = 70.0° and 0 = 50.0°, what is the refractive index of material 2? mirror
