Below is a visual model of the refraction of light as it strikes the interface between air-oil and then again at another interface of oil-water. The index of refraction of the oil is 1.48 and that of water is 1.33. The angle 0 is known to be 201)". (b air 3. Determine the speed of light in oil and in water. Explain your conclusions. b. Find the angle 13 at which the light refracts at the oil-water interface. Explain your work. c. Find the angle 93 at which the light refracts at the air-oil interface. Explain your work
