a/ Incident ray will inter fully destructively with the refrected ray, producing total internal refelction.
b/ Incident ray will bounce back on the intrface and travel along the same path but in the opposite direction

d/ All the light will be reflected back into the H2O
e/ The incident ray will interfere fully destructively with the transmitted ray, producing total internal reflection.
