What is the critical angle for the interface between water and diamond? To be internally reflected, the light must start in which material? (Bob Note: nwater = 1.33, ndiamond = 2.42. Since diamond has a larger index of refraction, the light ray will start and remain in the diamond for angles equal to, and larger than the critical angle?
