- Light propagates from air to oil (refracti0on oil n oil =1.49) with an angle of 36° with the surface of oil. The light propagates through oil/water (refraction index n water = 1.33). What is the angle of this light ray when it enters? (a) the oil, and then (b) the water? (c) What would be the refracted angle if the ray entered the water directly? (d) What would be the speed of the light in oil and water? Oil Air Water 36°An object is placed 10.1 cm in front of the cornea. (The cornea is thin ans has approximately parallel sides so that the reflection that occurs as light travels from air to cornea to aqueous humor is essentially the same as though the aqueous humor were directly in contact with the air. The aqueous humor has index of refraction n = 1.34 and the radius of curvature of cornea is 7.8 mm.) (a) What is the image distance for the image formed by the cornea alone?
