Water is optically denser than air. Let the incident ray AB (Fig. 1) strike the surface of water at B. Part of the light will be reflected, part absorbed, and part will pass through the water. This last part, the refracted ray, will take the direction BC. Draw the normal DE to the surface at B; then the angle ABD is called the angle of incidence, and the angle EBK the angle of refraction. The angle CBL, which is the difference between the angles of incidence and refraction, is the angle of deviation.
