A flashlight beam is emitted 7.53 cm beneath the (still) surface of the ocean by a scuba diver, and strikes the surface 6.75 cm away from the point directly above the flashlight. If this is the closest point (from "straight up") where total internal reflection occurs, calculate the index of refraction of the sea-water.
