characterizing the zero layer of the medium 



under consideration. 



The values found for the coefficients of refraction and reflection and also 

 for the multipher Cq are substituted in the appropriate form,ulas. The 

 intensity obtained for the wave relates to a point at a distance r from the 

 shot point along the profile calculated from the formula (5). 



Fig. 7. Curves for the coefficient of reflection (Pq' Pq') from a free surface. 



For two -layered media the formula (3) is converted into (6) and (7) for 

 single reflected waves, and into (8) and (9) for waves reflected n times
