Aray of light in water (index n1) is traveling upward toward the air and is incident at the water-air boundary at the critical angle. some oil (index n2) is now floated on the water. the angle between the direction of the ray in the oil and the normal direction is: a. sin-1(1/n1)b. sin-1(1/n2)c. sin-1(n1/n2)d. sin-1(1.00)e. sin-1(n2/n1)
