For glass-air interface,the critical angle is C.Will the critical angle for glass-water interface be greater or less than C?

A luminous object is paced just below a glass slab of thickness t. A circular opaque disc is placed vertically above on the surface of the glass-slab. If C is critical angle for glass-air interface, then predict the minimum radius of the opaque disc so that the object cannot be seen from any uncovered portion of the glass-slab.
