You have a beaker with a layer of olive oil floating on top of water. A ray of light travels through the oil and is incident on the water with an angle of 83.80. Using the index of refraction of the oil as 1.470 and the index of refraction of water as 1.333, determine the critical angle in oil for the oil-water interface. BC = Determine if the ray of light refracts into the water or reflects off the oil-water interface back into the oil. O refracts into the water O reflects back into the oil Additional Materials Reading Tutorial 8. [-/10 Points] DETAILS OSCOLPHYS2016 25.6.P.042.
