approximations, gives us Wp- = 2.97 x 10>, For a very large depth of water 
c takes the slightly smaller value 2.86 x 10> for the same thickness of 
top layer, We now calculate p and q by successive approximations from 
equations (4) and (8) and then calculate K, from 2quation (10). This _was 
done for some typical modes for the following three frequencies w= 10 F 
10% and 1.82 x 104, the first being telow the critical, and the other two 
above it. As it was found that these three frequencies gave a sufficiently 
good physical picture of the situation, no further calculations were carried 
out, Some specimen results are tabulated below.
