...critical angle : When a luminous ray passes iuto a medium of less refracting power, as from water to air, the angle of incidence is less than the angle of refraction. Hence, there is always an angle of incidence, SOB, such that the angle of refraction, A 0 B, is a right... | |

...refraction. When a ray of light passes from one medium into another which is less refracting, as from water into air, the angle of incidence is less than the angle of refraction. Hence when light is propagated in a mass of water there is always a value of the angle of incidence... | |
