Determine the maximum value of angle θ at which the upper face PQ of the glass rod can be cut so that a light wave traveling parallel to the vertical part of the rod will be reflected back into the rod when it strikes face PQ. Consider the rod immersed in water with a refractive index of 1.33 and the refractive index of rod material is 1.70.
