Take a length equal to two of the parts into which A-H was divided and draw a line parallel to the surface of the water from the circle to the extended line H-B, equal in length to two of these parts. This is the line C-G. Join C and B. This will give the direction of the beam of light after it has entered the water. The relation of the length of the line A-H and C-G to each other [ 47 ].
