The figure shows two prisms A and B. A monochromatic ray of light PO is incident at the face of the prism A. Complete the diagram to show the path of the ray till it emerges out of the prism B.
A ray of light strikes the surface of a rectangular glass slab such that the angle of incidence in air is
