Canola oil is less dense than water, so it floats on water, but its index of refraction is 1.47, higher than that of water. When you are adding oil and water to a bottle to make salad dressing, you notice a silvery reflection of light from the boundary between the oil and water. What is the critical angle for light going from the oil into the water?
A thin layer of oil of refractive index 1.25 is spread on the surface of water (n=1.33). If the thickness of the oil is 200 nm, then what is the wavelength of visible light in air that will be predominantly reflected from the top surface of the oil?
