1. A.    Half-cycle phase shifts occur at both the air-glass and glass-water interfaces.
2. B.     Half-cycle phase shifts occur at neither of the interfaces.
3. C.     A half-cycle phase shift occurs at the glass-water interface but not at the air-glass interface.
4. D.    A half-cycle phase shift occurs at the air-glass interface but not at the glass-water interface.
