Now this relation always holds for the one-dimensional case 
of "head-on" reflection (A = &! =0). The "head-on" 
values are given for oa 715 in Table 6a and for y = 2.00, 
1.40 in Table 6b. Furthermore, substituting relation (10a) 
in equation (9b) we find that these angles are equal also for 
an angle of incidence Cl, given by 
sin® q@ = 2-2 (10b
